lamber-ken opened a new pull request #2751: URL: https://github.com/apache/hadoop/pull/2751
## ISSUE https://issues.apache.org/jira/browse/HDFS-15882 ## NOTICE - `rw` Open for reading and writing. If the file does not already exist then an attempt will be made to create it. - `rws` Require that every update to the file's content or metadata be written synchronously to the underlying storage device. From the literal meaning of this variable `shouldSyncWritesAndSkipFsync`, we should use `rws` when shouldSyncWritesAndSkipFsync is false. We use SATA disk to store the journal node's data. It's not effective for improving RPC performance whether the `shouldSyncWritesAndSkipFsync` variable is true or false. it's caused by initializing RandomAccessFile incorrectly. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
