[jira] [Created] (PHOENIX-1677) Immutable index fails to build when number of guideposts are one half of thread pool size

Mujtaba Chohan created PHOENIX-1677:
---------------------------------------

             Summary: Immutable index fails to build 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.
