unnecessary exception catch in NNBench
--------------------------------------
Key: HADOOP-5963
URL: https://issues.apache.org/jira/browse/HADOOP-5963
Project: Hadoop Core
Issue Type: Bug
Components: test
Reporter: Boris Shkolnik
Priority: Minor
NNBench.createControlFiles - catches Exception (even though only IOException is
thrown) and then throws a new IOException with message from original. This
seems unnecessary and lossfull, because we loose stack info form the original
exception.
Suggestion - remove the catch part of try block.
