[jira] [Created] (HADOOP-9322) LdapGroupsMapping doesn't seem to set a timeout for its directory search

Harsh J created HADOOP-9322:
-------------------------------

             Summary: LdapGroupsMapping doesn't seem to set a timeout for its directory search
                 Key: HADOOP-9322
                 URL: https://issues.apache.org/jira/browse/HADOOP-9322
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
    Affects Versions: 2.0.3-alpha
            Reporter: Harsh J
            Priority: Minor


We don't appear to be setting a timeout via http://docs.oracle.com/javase/6/docs/api/javax/naming/directory/SearchControls.html#setTimeLimit(int) before we search with http://docs.oracle.com/javase/6/docs/api/javax/naming/directory/DirContext.html#search(javax.naming.Name,%20java.lang.String,%20javax.naming.directory.SearchControls).

This may occasionally lead to some unwanted NN pauses due to lock-holding on the operations that do group lookups. A timeout is better to define than rely on "0" (infinite wait).
