-----------------------------------------
[~jamestaylor] Test passes with your fix. I'll add a new patch for test in
ImmutableIndexIT or in its own class soon.
> 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
> Attachments: PHOENIX-1677_utest.patch, PHOENIX-1677_v2.patch

>
> 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.
