Resolution: Fixed
Modified to use one thread to retry JD WI requests
> UIMA DUCC: Optimize JP handling of no work from the JD
> ------------------------------------------------------

> Key: UIMA-4881
> URL: https://issues.apache.org/jira/browse/UIMA-4881
> Project: UIMA
> Issue Type: Improvement
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.1.0-Ducc
>
>
> When a JD returns no work, each worker JP thread sleeps for a bit and than
> asks JD again. At large scaleout many threads repeat this cycle causing the
> JD to spend a lot of time handling WI requests.
> Modify the JP to use a single thread in each process to retry request for
> work. While a single thread repeatedly retries other threads block until:
> 1) Retry thread receives work item
> 2) JP terminates
