[jira] [Created] (HBASE-9869) Optimize
HConnectionManager#getCachedLocation
Nicolas Liochon created HBASE-9869:
--------------------------------------
Summary: Optimize HConnectionManager#getCachedLocation
Key: HBASE-9869
URL: https://issues.apache.org/jira/browse/HBASE-9869
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
It javadoc says: "TODO: This method during writing consumes 15% of CPU doing lookup". This is still true, says Yourkit. With 0.96, we also spend more time in these methods. We retry more, and the AsyncProcess calls it in parallel.
I don't have the patch for this yet, but I will spend some time on it.
