Subject [jira] [Created] (PIG-3050) Fix FindBugs multithreading warnings
Date Thu, 15 Nov 2012 01:58:11 GMT
Cheolsoo Park created PIG-3050:

             Summary: Fix FindBugs multithreading warnings
                 Key: PIG-3050
                 URL: https://issues.apache.org/jira/browse/PIG-3050
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.11
            Reporter: Cheolsoo Park
            Assignee: Cheolsoo Park
             Fix For: 0.12

There was a race condition reported when running Pig in local mode on the user mailing list.
This motivated me to fix potential multithreading bugs that can be identified by FindBugs.

FindBugs identifies the following potential bugs:
# Mutable static field
# Inconsistent synchronization
# Incorrect lazy initialization of static field
# Incorrect lazy initialization and update of static field
# Unsynchronized get method, synchronized set method

There are in total 1153 warnings that FindBugs complains, but they're outside of the scope
of this jira.
