I trained a SimpleKMeans clusterer in Weka Explorer and saved the model to my computer. Now I want to use it in my Java code to cluster an instance I create but I get the following error when I try to deserialize it:
java.io.InvalidClassException: weka.core.Instance; weka.core.Instance;

where line 32 of my Test class is
Clusterer kmeans_temp = (Clusterer) weka.core.SerializationHelper.read("path/to/model/myclusterermodel.model");
Am I doing it right?
The problem was because I was using two different versions of WEKA to create the model and deserialize the model. I downloaded the source code for the version I used for WEKA explorer and problem solved.

This issue is due to the Usage of JMeter 2.11 with Java 8.
JMeter is compatible with Java 8 only starting from JMeter 2.12, so you need to upgrade to JMeter 2.12 and even better to most recent supported version of JMeter which is as of this writing JMeter 2.13.
Situation:
I'm using PostgreSQL 9.1 and now I'm using Pentaho Report Designer to create reports from a data warehouse stored on a database. This database is named bd-datawarehouse.
The problem I have is when I try to create a connection from the Pentaho Report Designer to bd-datawarehouse database. I've configured all the settings and everything seems correct, like the next image:
but when I click the Test button, it gives me the next error:

Hostname : localhost

Database name : bd-datawarehouse
You must know that all fields of settings are right (database name, port number, host name, user name and password).
Seeing the error, I've thought that the problem could be that I haven't the jdbc driver to connect a PostgreSQL database, so I've looked for it and I've done like the accepted answer of this question said: I've downloaded the driver for my postgresql 9.2 from here and I've put it on ...\biserver-ce\tomcat\lib\, but the problem persists.
I don't know how to solve it, because I don't understand so deeply which is the problem.
Any help would be appreciated!
report-designer\lib\jdbc\
or
bd-datawarehouse\lib\jdbc\
You need to place the appropriate jdbc jar file to above path. then you need to restart the pentaho reporting tool. It might be work. Its working for me.
I've downloaded the last version of the PostgreSQL JDBC 4.2 Driver and input it on the lib folder of the Database connection program, it worked for me :)
https://jdbc.postgresql.org/download.html#supported
It compiled fine a few days ago but something i did must have caused the issue but so much was done i am not too sure.
Error log here: http://pastebin.com/P1JHqDBD
If anyone needs anything else to solve the issue, let me know!
I tried deleting the unitcache folder in my HTML5 folder. didnt help, same isse. also tried cleaning.
Thanks in advance

I dont know what i did, i tried removing the war folder and put it back and suddenly it worked ....no idea :/
I'm developing some custom screens and custom actions and would like to create associations between them in much the same way that adding a "Create program group" screen suggests adding a "Create program group" action.
So I have a screen, and would like to associate an action with it. The action should be placed on the Installation screen. Within the screens bean info class, I've added the following line to the constructor:
setAssociatedAction(MyAction.class.getName(), InstallationScreen.class.getName());
This doesn't seem to do anything. I recompile, and re-add the screen to the installer, but it doesn't prompt me to add the action. I tried adding the same settings to the action's constructor, thinking that perhaps both need to create an association with each other to work:
setAssociatedScreen(MyScreen.class.getName());
setInstallerTargetScreen(InstallationScreen.class.getName());
It didn't help either. I even tried doing the reverse by creating the action to see if it requests that the screen be created as well, but no luck there. Luckily, setting the installer target screen worked as expected.
I've tried the following as well:
Simple and canonical names for the class name.
The bean info classes, just incase.
I'm not sure what I'm doing wrong, if I am doing anything wrong. The documentation doesn't elude to any additional dependencies:
ScreenBeanInfo
ActionBeanInfo
Hopefully this isn't a bug.
Thanks in advance!
EDIT:
I was about to resolve this, but only as an extension to install4j. I used the wrong class when specifying the Bean class in the BeanInfo.
I had:
public MyActionBeanInfo() {
super("Title", "Description", "Category", false, true, null, MyActionBeanInfo.class);
}
Instead of:
public MyActionBeanInfo() {
super("Title", "Description", "Category", false, true, null, MyAction.class);
}
As a small enhancement, would it be possible to throw an exception, perhaps an IllegalArgumentException, from the super constructor if it is not a valid Bean class?
BUT!
I still received a ClassNotFound and NullPointer exception when not used as an extension.

This is a bug in install4j. Associated screens and actions cannot be loaded if the bean is added on the Installer->Custom code & Resources tab.
This will be fixed in 5.1.7.
Currently I encounter some problems when I try to run Spark with Cassandra on standalone mode.
Initially, I run successfully with parameter mater="local[4]" in SparkContext.
Then, I try to move to standalone mode. What I used are:
Ubuntu: 12.04
Cassandra: 1.2.11
Spark: 0.8.0
Scala: 2.9.3
JDK: Oracle 1.6.0_35
Kryo: 2.21
At first, I got "unread block" error. As suggestion in other topic I change to use Kryo serializer and add Twitter Chill. Then, I get the " Failed to register spark.kryo.registrator " in my console and the Exception as below:
13/10/28 12:12:36 INFO cluster.ClusterTaskSetManager: Lost TID 0 (task 0.0:0)
13/10/28 12:12:36 INFO cluster.ClusterTaskSetManager: Loss was due to java.io.EOFException

Someone also encountered the EOFException in spark before, the answer is not register the registrator correctly. I register the Registrator following the Spark guide. Registrator as below:
class MyRegistrator extends KryoRegistrator {
override def registerClasses(kryo: Kryo) {
kryo.register(classOf[org.apache.spark.rdd.RDD[(Map[String, ByteBuffer], Map[String, ByteBuffer])]])
kryo.register(classOf[String], 1)
kryo.register(classOf[Map[String, ByteBuffer]], 2)
}
}
And I also set the property just as the guide does.
System.setProperty("spark.serializer", "org.apache.spark.serializer.KryoSerializer")
System.setProperty("spark.kryo.registrator", "main.scala.MyRegistrator")
Can anyone give me some hints where I did wrong?
Thanks.
Based on my experience, the reasons to get the "EOFException" and the "data unread block" are the same. They lack some libraries when running on the clusters. The most wired thing is that I have add the libraries with "sbt assembly" in spark and the libraries are actually existing in the jars folder. But the spark still cannot find and load them successfully. Then I add the libraries in the spark context, it works. That means I need to transport the libraries to each nodes by specifying in the code.
