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:
Error connecting to database [conexion-dw-reporting] : org.pentaho.di.core.exception.KettleDatabaseException:

Hostname : localhost
Port : 5432
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 :/
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)

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.
