Subject [jira] [Created] (HBASE-14512) Cache UGI groups
Date Tue, 29 Sep 2015 21:01:04 GMT
Elliott Clark created HBASE-14512:

             Summary: Cache UGI groups
                 Key: HBASE-14512
                 URL: https://issues.apache.org/jira/browse/HBASE-14512
             Project: HBase
          Issue Type: Bug
          Components: Performance, security
    Affects Versions: 1.2.0
            Reporter: Elliott Clark
            Assignee: Elliott Clark
             Fix For: 2.0.0, 1.2.0, 1.3.0

Right now every call gets a new User object.
We should keep the same user for the life of a connection. We should also cache the group
names. However we can't cache the groups for forever as that would mean groups don't get refreshed
every 5 mins.
