Thejas M Nair updated PIG-1448:
-------------------------------
Attachment: multi_oom_filt.pig
multi_oom_filt.pig is a query that reproduces this problem for a filter query.
There is a bincond in the filtercondition, and one side of the bincond does not
get evaluated and detached. The query runs out of memory in reduce. With fix to
call detach from POFilter, the query succeeds.
> Detach tuple from inner plans of physical operator

> This is a follow-up on PIG-1446 which only addresses this general problem for
> a specific instance of For Each. In general, all the physical operators which
> can have inner plans are vulnerable to this. Few of them include
> POLocalRearrange, POFilter, POCollectedGroup etc. Need to fix all of these.
