[jira] [Commented] (PIG-5043) Slowstart not applied in Tez with PARALLEL clause and auto parallelism not applied for UnorderedPartitioned

    [ https://issues.apache.org/jira/browse/PIG-5043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15592854#comment-15592854 ] 

Daniel Dai commented on PIG-5043:
---------------------------------

Do you mind adding a test case for union (HashValuePartitioner) with auto parallelism?

> We enable auto parallelism only if there is no custom partiioner, but in case of UnorderedPartitioned it always had RoundRobinPartitioner.
> VertexManager plugin configuration is not overridden if there is no auto parallelism. So slow start settings are not applied.
