Nicolas Liochon created HBASE-9987:
--------------------------------------
Summary: Remove some synchronisation points in HConnectionManager
Key: HBASE-9987
URL: https://issues.apache.org/jira/browse/HBASE-9987
Project: HBase
Issue Type: Bug
Components: Client
Affects Versions: 0.96.0, 0.98.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Fix For: 0.98.0, 0.96.1
Attachments: 9987.v1.patch
Change a Map to a concurrentMap
Removed the "cachedServer (introduced in HBASE-4785). I suspect that this
function is not needed anymore as we also have a list of dead servers, and
accessing the list is not blocking. I will dig into this more however.
The patch gives a 10% improvement with the NoClusterClient.
