[jira] [Commented] (TEZ-2366) Pig tez MiniTezCluster unit tests
fail intermittently after TEZ-2333
[ https://issues.apache.org/jira/browse/TEZ-2366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522408#comment-14522408 ]
Hitesh Shah commented on TEZ-2366:
----------------------------------
NodeId is host + port. Shuffle port could also be used - we are already using hostname matching in any case for checking whether this can be a local fetch.

> To reproduce that in Pig test, using the following commands:
> svn co http://svn.apache.org/repos/asf/pig/trunk
> ant -Dhadoopversion=23 -Dtest.exec.type=tez -Dtestcase=TestTezAutoParallelism test
> Note in Pig codebase, we already set TEZ_RUNTIME_OPTIMIZE_LOCAL_FETCH to "true" (http://svn.apache.org/viewvc/pig/trunk/src/org/apache/pig/backend/hadoop/executionengine/tez/TezLauncher.java?view=markup). I tried changing TEZ_RUNTIME_OPTIMIZE_LOCAL_FETCH to "false" in Pig and does not help.
