James Taylor updated PHOENIX-1677:
----------------------------------
Summary: Immutable index deadlocks when number of guideposts are one half of thread pool
size (was: Immutable index fails to build when number of guideposts are one half of thread
pool size)
> Immutable index deadlocks when number of guideposts are one half of thread pool size
> ------------------------------------------------------------------------------------
>
> Key: PHOENIX-1677
> URL: https://issues.apache.org/jira/browse/PHOENIX-1677
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 5.0.0, 4.3
> Reporter: Mujtaba Chohan
> Assignee: James Taylor
>
> If total number of parallel iterators + mutation count exceeds Phoenix thread pool size
then immutable index remains at 0 rows with no activity on client and server.
> Ex. Only with guide post count of 64 or lower does immutable index gets build with default
128 thread pool. By changing guide post width to get with >64 guideposts, index fails to
build. Also if thread pool size is lowered from 128 then index fails to build for 64 guide
posts.
> Let me know if you need a utest as I think it would be easy to repro in it too.
