----------------------------------
Summary: 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
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.
