Kihwal Lee commented on HDFS-9828:
----------------------------------
For one, open (i.e. getBlockLocations) is usually considered important part of
security audit. In certain cases, the law requires you to have all such
activities on record. It is also very important for the organizations who do
not enforce security at the time of access, but rely on audit to spot
violations.
> Change all read only operation audit log to debug level

> Audit log should only log important operations such as create new file/folder
> , , delete file/folder and so on, but the read only operation need to be kept
> in log, otherwise the log size will become very big quickly if heavy load.
