Summary: UIMA-DUCC: Fix race in agent
Key: UIMA-6061
URL: https://issues.apache.org/jira/browse/UIMA-6061
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 3.0.1-Ducc
There is a race condition in agent which leads to incorrect process reporting
in Duccmon. In this scenario the following happened:
* agent started JP
* JP reported Initializing state which agent then publishes to the OR
* JP reported Running state but immediately after died due to process error.
The agent detected process termination (before publishing Running to OR) and
changed state to failed with reason Unknown
There is a small window where the race can occur.
