Samarth Jain commented on PHOENIX-1435:
---------------------------------------
FYI, the request stack above corresponds for the case when the query fails
because of 10k guide posts. Reducing the guide posts to 1K, I don't see the
orphan memory chunk warnings. So possibly we are missing out on closing some
iterators in case of failure.
> Create unit test that uses 15K guideposts

> Issue Type: Bug
> Reporter: James Taylor
> Assignee: Samarth Jain
>
> We're seeing memory issues when 14K guideposts are used to execute a query.
> Although other issues are contributing to the high number of guideposts
> (PHOENIX-1434), and we don't need to execute some LIMIT queries in parallel
> (PHOENIX-1432), we should still get to the bottom of why this is causing
> memory and/or CPU issues.
> One question with this kind of scenario - why didn't the query get rejected,
> as it seems like it would fill up the queue past the allowed 5000 threads?
> Also, do the temp files get cleaned up in this scenario?
