Subject [jira] [Commented] (HIVE-13605) TestDbTxnManager failing intermittently
Date Mon, 02 May 2016 13:39:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13605?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15266624#comment-15266624
] 

Zoltan Haindrich commented on HIVE-13605:
-----------------------------------------

this "already exists problem" can be easily addressed by adding cleanup prior to create...but
thats a bit ugly -- it might not solve the issue; but might make the view a bit more cleaner

i think when the testdbtxnmanager fails...the following test also fails...and it flaps more
frequently

http://ec2-54-177-240-2.us-west-1.compute.amazonaws.com/job/PreCommit-HIVE-MASTER-Build/125/testReport/org.apache.hadoop.hive.ql.security/TestStorageBasedMetastoreAuthorizationReads/history/#

i'm not sure how ptest executes the tests...i've seen connection refused messages earlier;
and it was caused by some bad xml inside the common module; which ended up earlier in the
classpath by mistake...without the stderr/stdout i can't tell its connected or not
