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.
> SkewedJoin_14 is failing with spark exec type
