Alina Abramova commented on HIVE-12244:
---------------------------------------

I see that most test that passed locally are failed by Jenkins. For example:
I ran tests with   -Dqfile_regex=smb_mapjoin.* 
Tests run: 33, Failures: 3, Errors: 0, Skipped: 0,
Failed tests :
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin11
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin13
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin15

>From Jenkins message failed tests:
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin1
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin10
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin11
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin2
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin3
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin4
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin5
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin6
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin7
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin8
org.apache.hadoop.hive.cli.TestCliDriver.testCliDriver_skewjoin_mapjoin9

I do not understand what happens and why these tests results are different. 
Could somebody run this part of tests (  -Dqfile_regex=smb_mapjoin.* ) locally 
and show me results please? Maybe I do something wrong.

> In Hive often String is used for representation path and it causes new issues.
> We need to compare it with equals() but comparing Strings often is not right 
> in terms comparing paths .
> I think if we use Path from org.apache.hadoop.fs we will avoid new problems 
> in future.
