Mingliang Liu updated HADOOP-13105:
-----------------------------------
    Attachment: HADOOP-13105.004.patch

Thank you [~cnauroth] for your comment. Sorry I was not aware of the {{final}} 
variable problem when sharing with a nested thread in Java 7. I should have 
fixed the problem if I had the chance to build against {{branch-2}}. I was 
spoiled by the Java 8 and especially IntelliJ IDE.

The v4 patch simply added two "final" keyword to the {{finLatch}} varaible in 
the test. I tested the patch on both trunk (Java 8) and trunk (Java 7), and it 
looked good.

> {{LdapGroupsMapping}} currently does not set timeouts on the LDAP queries.  
> This can create a risk of a very long/infinite wait on a connection.
