> UIMA-AS parallel processing is broken
> -------------------------------------
>
> Key: UIMA-3644
> URL: https://issues.apache.org/jira/browse/UIMA-3644
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Affects Versions: 2.4.2AS
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.5.0AS
>
>
> It appears that the parallel step involving fast AEs is broken. The UIMA-AS
> logs "preexisting FS encountered but not allowed ".
> A user explains the problem as follows:
> "The exception happens randomly. It happens when UIMA gets a response from
> one of the parallel annotators before it is done sending the request to all
> parallel annotators.
>
> à request goes to annotator 1
> à request goes to annotator 2
> ß response comes from annotator 1
> à request goes to annotator 3 (CAS sent to annotator 3 is messed up, it
> includes stuff received from annotator 1)
> …
> ß response comes from annotator3 -à bogus exception: preexisting FS
> encountered but not allowed "
> This probably needs a new junit test case before a fix is made.
