Hi Suraj, These tests have been executed successfully of late in the precommit build runs, for e.g. http://ec2-174-129-184-35.compute-1.amazonaws.com/jenkins/job/PreCommit-HIVE-TRUNK-Build/lastStableBuild/testReport/org.apache.hive.hcatalog.pig/TestHCatLoader/ and in my local machine.
So most likely, this is a setup issue.

This solved the problem of debugging. Now am facing one more issue. There were some test failures. Am looking at it, however, I will paste the error below if it is common issue(so I don't reinvent the wheel again): Listening for transport dt_socket at address: 8000 Running org.apache.hive.hcatalog.pig.TestHCatLoader Tests run: 60, Failures: 9, Errors: 22, Skipped: 3, Time elapsed: 1,428.185 sec <<< FAILURE! - in org.apache.hive.hcatalog.pig.TestHCatLoader testProjectionsBasic[0](org.apache.hive.hcatalog.pig.TestHCatLoader) Time elapsed: 8.82 sec <<< ERROR! org.apache.pig.impl.logicalLayer.FrontendException: Unable to open iterator for alias Y2 at org.apache.pig.PigServer.openIterator(PigServer.java:872) at org.apache.hive.hcatalog.pig.TestHCatLoader.testProjectionsBasic(TestHCatLoader.java:462) testConvertBooleanToInt[0](org.apache.hive.hcatalog.pig.TestHCatLoader) Time elapsed: 4.926 sec <<< ERROR! org.apache.pig.impl.logicalLayer.FrontendException: Unable to open iterator for alias data at org.apache.pig.PigServer.openIterator(PigServer.java:872) at org.apache.hive.hcatalog.pig.TestHCatLoader.testConvertBooleanToInt(TestHCatLoader.java:571) testReadDataBasic[0](org.apache.hive.hcatalog.pig.TestHCatLoader) Time elapsed: 22.188 sec <<< ERROR! org.apache.pig.impl.logicalLayer.FrontendException: Unable to open iterator for alias X at org.apache.pig.PigServer.openIterator(PigServer.java:872) at org.apache.hive.hcatalog.pig.TestHCatLoader.testReadDataBasic(TestHCatLoader.java:294) testColumnarStorePushdown[0](org.apache.hive.hcatalog.pig.TestHCatLoader) Time elapsed: 3.953 sec <<< FAILURE! java.lang.AssertionError: null at org.junit.Assert.fail(Assert.java:86) at org.junit.Assert.assertTrue(Assert.java:41) at org.junit.Assert.assertTrue(Assert.java:52) at org.apache.hive.hcatalog.pig.TestHCatLoader.testColumnarStorePushdown(TestHCatLoader.java:504) Thanks!

Now,If I want to debug the hive-hcatalog-pig-adapter/org.apache.hive.hcatalog.pig.HCatLoader class, I tried to run /hive-hcatalog-pig-adapter/org.apache.hive.hcatalog.pig.TestHCatLoader by enabling few debug points. Am getting following error when I Right-Click on TestHCatLoader and Select JUnit Test: FAILED: NullPointerException Non-local session path expected to be non-null 15/05/08 12:24:37 ERROR ql.Driver: FAILED: NullPointerException Non-local session path expected to be non-null java.lang.NullPointerException: Non-local session path expected to be non-null While being in eclipse am able to run the goal "test -Dtest=org.apache.hive.hcatalog.pig.TestHCatLoader -Phadoop-2" from itests directory successfully. But the debug point is never caught during the testing. How can I line by line debug any class such as this HCatLoader loader class from eclipse? Any help is appreciated! -- Thanks Suraj Nayak M -- Thanks Suraj Nayak M
