IOException is abused in FSDirectory
------------------------------------
Key: HADOOP-4985
URL: https://issues.apache.org/jira/browse/HADOOP-4985
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Reporter: Tsz Wo (Nicholas), SZE
In FSDirectory, quite a few methods are unnecessary declared with "throws
IOException". In some cases, it can just be removed without causing any
compilation problem. In some other cases, it can be replaced with a specific
subclass like QuotaExceededException.
