-------------------------------------
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.
