---------------------------------
Summary: Several HBase write perf improvement
Key: HBASE-6968
URL: https://issues.apache.org/jira/browse/HBASE-6968
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
There are two improvements in this jira:
1) Change 2 hotspot synchronized functions into double locking pattern. So it
shall remove the synchronization overhead in the normal case.
2) Avoid creating HBaseConfiguraiton object for each HLog. Every time when
creating a HBaseConfiguraiton object, it would parse the xml configuration
files from disk, which is not cheap operation.
