---------------------------------

             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.
