tPigload failed with HCatLoader Load function

[Anonymous]

Hi,
tPigload fails to connect to Hive table with HCatLoader Load function, but retrieving the table via Pig console succeeds. Appreciate your help in regards to how to troubleshoot the issue.
Version of Talend Open Studio: 5.5.0
Hadoop: HDP 2.1 for Windows
1. retrieve table from Pig console - succeeded
a = LOAD 'Talend.weblog' using org.apache.hcatalog.pig.HCatLoader();
2. Use tPigload & tPigStoreResult components - failed

I find the error is exactly the same with as error described at http://www.srccodes.com/p/article/46/noclassdeffounderror-org-apache-hadoop-service-compositeservice...
However, I added the CLASSPATH property in yarn-site.xml according to the advice of the post, the error still remains. could anyone shed me a light?
thanks,
Mo

I think I could find the cause.
After install trial Enterprise studio, I am now able to trace into the job code. I found that that Talend studio ignores the classpath setting in ?yarn-site.xml? but always adds below classpath as the properties in the function tPigLoad_1Process() , which is actually wrong classpath for HDP Windows.
props_tPigLoad_1.put("yarn.application.classpath", "/etc/hadoop/conf,/usr/lib/hadoop/*,/usr/lib/hadoop/lib/*,/usr/lib/hadoop-hdfs/*,/usr/lib/hadoop-hdfs/lib/*,/usr/lib/hadoop-yarn/*,/usr/lib/hadoop-yarn/lib/*,/usr/lib/hadoop-mapreduce/*,/usr/lib/hadoop-mapreduce/lib/*");
The advice/help I need
1. Is this a bug for tPigload component? Where can I report this issue?
2. The debug trace stops at ?pigServer_tPigLoad_1.executeBatch();? which tell me that ?Source not found? for the file PigServer.calss. where can I download the source of PigServer.calss so that I can continue trace to locate the problematic call?
Thank you,
Mo
