--------------------------------
Resolution: Fixed
> DUCC RM: share count goes negative
> ----------------------------------
>
> Key: UIMA-3939
> URL: https://issues.apache.org/jira/browse/UIMA-3939
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 1.0.0-Ducc
> Reporter: Jim Challenger
> Assignee: Jim Challenger
> Fix For: 1.1.0-Ducc
>
>
> When a node leaves because of ping timeout and then returns, the total share
> count isn't being adjusted correctly on return. This causes more
> subtractions than additions and the share count falls negative, rendering the
> cluster unschedulable.
> Fix is in NodePool.nodearrive(), be sure to alwasys increment shares in all
> cases of a node returning.
