Hbase Connectivity issue with Neo4j Database

Hi All,
I'm working on a Windows 7 64 bits and using TOS for Big Data 5.5
I created a new database using Neo4j 2.1.1
Hbase Version- hbase-0.94.8
hbase.zookeeper.quorum- ""
hbase.zookeeper.clientPort - "2181
Job name : HbaseJobTest
I want to read from a hbase table to a Neo4j although I am getting a connection error. Here is my execution log:
Error Description :-
""Starting job HbaseJobTest at 11:11 17/06/2014.
Error: Could not find or load main class test.hbasejobtest_0_1.HbaseJobTest
Job HbaseJobTest ended at 11:11 17/06/2014. ""
PFA the image for connection arrangement.
So , would any one have an idea how to fix this issue? or
How may I use the tHBase* components to establish this?
Many Thanks

Re: Hbase Connectivity issue with Neo4j Database

I have faced this error many times, if the job building is not properly handled by talend. Re-executing the job fixed it autmatically... have you tried closing and opening it again?

Now after re-executing so many time I'm getting error like

Starting job hbase_input_output at 13:53 17/06/2014.

Re: Hbase Connectivity issue with Neo4j Database

Are you using direct connection to Neo4j, if so try connect to Neo4j Rest API (server URL) instead, like the image.
