Requesting review on this patch.
The style check failures are from legacy code and not introduced in this
patch specifically.
The unit test failures are also unrelated (the same patch passed the unit
tests previously and no logic changes done in the follow up patch - only style
changes fixed)
> Improve NNThroughputBenchmark to allow non super user to use the tool
> ---------------------------------------------------------------------
>
> Key: HDFS-17439
> URL: https://issues.apache.org/jira/browse/HDFS-17439
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: benchmarks, namenode
> Reporter: Fateh Singh
> Priority: Major
> Labels: pull-request-available
>
> The NNThroughputBenchmark can only be used with hdfs user or any user with
> super user privileges since entering/exiting safemode is a privileged
> operation. However, when using super user, ACL checks are skipped. Hence it
> renders the tool to be useless when testing namenode performance along with
> authorization frameworks such as Apache Ranger / any other authorization
> frameworks.
> An optional argument such as -nonSuperUser can be used to skip the statements
> such as entering / exiting safemode. This optional argument makes the tool
> useful for incorporating authorization frameworks into the performance
> estimation flows.
