[jira] [Reopened] (PIG-5170) SkewedJoin_14 is failing with spark exec type

["Xianda Ke (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-5170?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Xianda Ke reopened PIG-5170:
----------------------------
      Assignee: Xianda Ke

after apply the outer join patch. other SkewdJoin e2e cases passed, but SkewedJoin_14 still failed.  after investigation, this bug is similar with PIG-4587.

For the streaming table, since more than one reducer can be associated with a key, the streamed table records (that match the key) needs to be copied over to each of these reducers(see PIG-4858 for details).  if it is outer join, no need to join the null left record to all the copied records, only join the first one.

i reopen this jira, and will update the fix patch soon.
