Summary: UIMA-DUCC: Pull service not failing fast on
initialization error
Key: UIMA-5877
URL: https://issues.apache.org/jira/browse/UIMA-5877
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Jerry Cwiklik
Assignee: Jerry Cwiklik
Fix For: 2.2.3-Ducc
With multiple threads initializing, the protocol handler serializes call to
processor.initialize() so that only one thread is allowed to initialize at a
time.
If initialization fails the design goal is for the remaining threads to
fail-fast if a previous thread failed. The check for error was in the wrong
place in the DefaultServiceProtocolHandler.initialize(). Modify to do the check
*after* a thread acquires a lock as in the below snippet:
try {
// use a lock to serialize initialization one thread at a time
initLock.lock();
if (initError) {
return;
}
processor.initialize();
