@fateh288 This change LGTM. As the last commit was a little old, could you
merge in trunk or rebase on trunk and push the change so the CI runs again.
This will avoid any problems that may occur due to some change on trunk over
the last couple of months. Thanks!
> 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.
