-----------------------------------
Summary: UIMA-DUCC: The JP code not handling
HttpHostConnectException
Key: UIMA-5469
URL: https://issues.apache.org/jira/browse/UIMA-5469
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.1-Ducc
Error handling for HttpHostConnectionException is incomplete. When the
HttpClient looses connection to the JD's Web Server, the above exception is
thrown. There is an explicit
catch() to deal with it but all it does now is just log the problem once. So
what happens in this scenario is that a thread fails over and over again.
What should happen here is that a single thread should attempt connection
recovery sleeping for awhile (default=60sec) and try again. Other threads (if
scaleout > 1), should block doing nothing until a thread doing the retry
succeeds.
