Review request for ranger.
Bugs: RANGER-1501
https://issues.apache.org/jira/browse/RANGER-1501
Repository: ranger
Description
-------
The reason is that HDFS file stream's flush() call does not really flush the
data all the way to disk, nor even makes the data visible to HDFS users. See
the HDFS semantics of the flush/sync at
https://issues.apache.org/jira/browse/HADOOP-6313.
Consequently the audit logs on HDFS won't be visible/durable from HDFS client
until the log file is closed. This will, among other issues, boost chances of
losing audit logs in case of system failure.
