----------------------------------------
Summary: Performance improvement in CodecPool
Key: HADOOP-10095
URL: https://issues.apache.org/jira/browse/HADOOP-10095
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 2.2.0, 3.0.0
Reporter: Nicolas Liochon
Assignee: Nicolas Liochon
Priority: Minor
Fix For: 3.0.0, 2.2.1
CodecPool shows up when profiling HBase with a mixed workload (it says we spend
1% of the time there).
It could be a profiler side effect, but on the other hand we can save some
'Map#contains'.
