> add a flag and disable some object pools in LLAP until further testing
> ----------------------------------------------------------------------
>
> Key: HIVE-18837
> URL: https://issues.apache.org/jira/browse/HIVE-18837
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Priority: Major
> Attachments: HIVE-18837.patch
>
>
> There appears to be some subtle concurrency issue in FixedSizedObjectPool
> that happens with multiple consumers where some object may be retrieved
> twice.
> Unfortunately running a load test for hour(s) does not trigger it for me and
> overall it happens extremely rarely on non-specific tests; adding debug info
> at this level is a little bit difficult to determine how it could have
> happened and interlocked operations in the trace may actually eliminate the
> issue. I suspect it has something to do with aggressive assumptions made for
> locking and array elements and the memory model. Maybe that can be simplified
> without much perf loss.
> Anyway, for now we will disable the pools where multiple consumers use them.
> Need to test perf to see if these two pools even matter; if so, we can
> simplify the model as per above or debug the issue in some way.
