I want to fork the waves blockchain in which I wanted to change the coin. I first change the name of coin in waves node
link : https://github.com/wavesplatform/Waves/blob/version-1.2.x/node/src/main/scala/com/wavesplatform/transaction/assets/exchange/AssetPair.scala
according to the link I deployed on windows and I got this error.

I am trying to setup drillv1.18 running. Facing the error below.
The drill-override.conf points to the zookeeper which runs on port 12181. On starting in distributed mode, it fails with the following log output. But the embedded mode has no issues.
It appears like permission issue, but both zookeeper, drill, zookeeper data-dir all are running under the same user.

Version 1.17 has no issues in starting in distributed mode.
The issue here is with the zookeeper version. Perhaps you use 3.4.X version, but the current version of Drill requires 3.5.X. As a workaround, you may replace zookeeper jar in jars/ext/zookeeper-3.5.7.jar and jars/ext/zookeeper-jute-3.5.7.jar with the jars that corresponds to your zookeeper version.
In Addition to the answer of Vova Vysotskyi, you may find more information in Drill documentation about this issue:
https://drill.apache.org/docs/distributed-mode-prerequisites/
Starting in Drill 1.18 the bundled ZooKeeper libraries are upgraded to version 3.5.7, preventing connections to older (< 3.5) ZooKeeper clusters. In order to connect to a ZooKeeper < 3.5 cluster, replace the ZooKeeper library JARs in ${DRILL_HOME}/jars/ext with zookeeper-3.4.x.jar then restart the cluster.
I am currently trying to run Protractor test script using selenium grid. My goal is to distribute Protractor test scripts to multiple nodes running under different flavor of OS. It should also run different parts of test script in parallel to save execution time. Current setup works when I use webdriver-manager to distribute test with multiple instances, but webdriver-manager would let me use only one node. I know it's possible to overcome this issue with selenium grid, but I am having following errors test console:

this is my current configuration:
seleniumAddress: 'http://localhost:4444/wd/hub',
chromeDriver: './node_modules/protractor/selenium/chromedriver_2.21',
capabilities: {
'rootElement': '*[ng-app]',
'browserName': 'chrome', // chrome, firefox, or phantomjs
'shardTestFiles': true,

}
I ran the following command line to launch hub:
java -jar /Users/xxx/selenium-server-standalone-3.0.0-beta2.jar -role hub
and following is for running node:
java -jar /Users/xxx/selenium-server-standalone-3.0.0-beta2.jar -role node -hub http://localhost:4444/grid/register
Chrome driver is under: /node_modules/protractor/selenium/chromedriver_2.21
Has anyone successfully configure protractor with selenium grid?
Webdriver_manager is bundled in npm as a quick solution for starting server and is not a comprehensive solution as Selenium Grid. Grid should be used for all professional distributed execution environment.
Check this link for response from Julie
Webdriver-Manager doesn't have options for hub & node
And regarding Protractor with Selenium Grid, I did use local Grid and also Sauce Labs.
You should pass the chrome driver property when initializing the node.
java -jar /Users/xxx/selenium-server-standalone-3.0.0-beta2.jar -role node -hub http://*******:4444/grid/register/ -Dwebdriver.chrome.driver=C:/Users/<>/AppData/Roaming/npm/node_modules/protractor/selenium/chromedriver.exe
The protractor Conf - chromedriver option is not passed over grid and it works for only webdriver-manager.
I'm new in Titan world. I would like to import data stored in GraphML file into a database.
I downloaded titan-1.0.0-hadoop1
I run ./titan.sh
I run ./gremlin.sh

Next, I wrote:
graph.io(IoCore.graphml()).readGraph("/tmp/file.graphml")

You need to create a graph. the graph keyword isn't declared anywhere in your script.
This is briefly covered in the Titan Server documentation, but it is easily overlooked.
The :> is the "submit" command which sends the Gremlin on that line to the currently active remote.
In step 5, you need to submit your script command to the remote server. In the Gremlin Console, you do this by starting your command with :submit or :> for shorthand.
:> graph.io(IoCore.graphml()).readGraph("/tmp/file.graphml")
If you don't submit the script to the remote server, the Gremlin Console will attempt to process the script within the console's JVM. graph is not defined locally, and that is why you saw the error in step 6.
Update: Based on your gremlin-server.log it looks like the issue is that the user that starts Titan with ./bin/titan.sh start doesn't have the appropriate file permissions to create the directory (db/berkeley) used by the default graph configuration (titan-berkeleyje-server.properties). Try updating the file permissions on the $TITAN_HOME directory.

Using OrientDB .Net binary (C# driver) in Windows Vista. This was working fine until recently. Not sure what broke it...
Resetting TCP/IP using NetShell utility did not help.
Any help is highly appreciated.
The problem was with the AVG anti-virus program that is blocking the socket. Added an exception in the program for localhost to fix the problem.
I wanted to lern xtext, for many years i lerned xpand and xtend and worked fine, but xtext seems to replaced the other both. And the xtext way looks fine to me.
As start i read follwing Tutorials: http://www.eclipse.org/Xtext/documentation/101_five_minutes.html, Including "15 Minutes Tutorial" and "15 Minutes Tutorial - Extended" and others. So i created a simple "Model"
grammar org.bs.test.Test with org.eclipse.xtext.common.Terminals
generate Test "http://www.bs.org/test/Test"
Test:
main=TMain;
TMain:
'main' name=ID
'done';
Generated on following way: "GenerateTest.mwe2" > right click > 'Run As' → 'MWE2 Workflow'.
Then made a copy of the Project. It was already my second or third try to find out what i made wrong.
Now i changed in the model following line: "main=TMain;" to "main=TMain?;". Then i used 'MWE2 Workflow' again, which run successful, but after running following happens:
Everthing files under 'src-gen/org/bs/test/Test/' and files in the subfolders 'impl' and 'util' are deleted. So they get deleted, then i copied the saved project and try following action on "Test.xtext" > right click > 'Run As' → 'Generate Xtext Artifacts', which result in the same.
There are two question for me:
1) What is the difference between "Generate Xtext Artifacts" and "MWE2 Workflow" and when did i do need them. I cannot figure that out on the Tutorial and especialy when to use them.
2) What did i wrong, and what i have to do to create generate the elements from the changed model
I could not find much on this, i hope someone could help me. I did not find something to both question.
EDIT 1:
When i create a complete new test project it works:
project name: org.test
name: org.test.MyTest
extensions: mytest
with following xtext:
grammar org.test.MyTest with org.eclipse.xtext.common.Terminals
generate myTest "http://www.test.org/MyTest"
Test:
main=TMain;
TMain:
'main' name=ID
'done'
But when i do the same with following input:
Project name: org.bs.craass
Name: org.bs.craass.CraAss
Extension: craass
xtext:
grammar org.bs.craass.CraAss with org.eclipse.xtext.common.Terminals
generate craAss "http://www.bs.org/craass/CraAss"
CraAss:
main=CAMain;
CAMain:
'main' name=ID
'done';
Later i will try following: install a new eclispe emf and create a new workspace.
EDIT2:
So i tested a new workspace, there it look liks, that it is working. Perhaps something with the old workspace. Like in a comment, in the orginal workspace, after i get a good "version", i wanted to put it on git (learning reason). Since then this not working anymore. Here some output of the generation:

EDIT 3:
I do not know why, but it accept now the old xtext file i created and while running it occurs following error (but seems to have no big impact), complete log:

The trouble seems, that i have following:
grammar org.bs.craass.CraAss with org.eclipse.xtext.common.Terminals
but on the other side:
terminal INTEGER : '-'?('0'..'9')+;
terminal VAR_TERMINAL : '_' ('a'..'z'|'A'..'Z'|'_'|'0'..'9')*;
terminal REGISTER_TERMINAL : ('ax' | 'bx' );
terminal FUNCTION_TERMINAL : (('a'..'z'|'_'|'0'..'9')*'.')?('a'..'z'|'A'..'Z'|'_'|'0'..'9')*;
And in the org.eclipse.xtext.common.Terminals is
terminal INT returns ecore::EInt: ('0'..'9')+;
But i have no what to do with it.
The Problem itself, while generating everthing in srce-gen/, except the generated java files under src-gen/org.bs.craass.craAss and subfolder. Now there are created, too. So more i try to find out, so less the error was reproducable. Well, i will see, when i push it to git again, perhaps the error comes back.
So far thanks
running the workflow directly or calling generate language artefacts does the very same. the workflow reads your Xtext file and generates all infrastructure Xtext provides for your language. thus you have to call it if you change your grammar or the workflow itself. if you have a misconfiguration on your language or a broken grammar the generation may fail. also the workflow may refer to project names which may have to be adopted as well (dont know how you do the copy and paste - you should use the Xtext Project wizard to create the project to be safe)
