> Key: HDFS-2117
> URL: https://issues.apache.org/jira/browse/HDFS-2117
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: data-node
> Affects Versions: 0.20.203.1
> Reporter: Eli Collins
> Assignee: Eli Collins
> Priority: Minor
> Fix For: 0.20.205.0

> In branch-0.20-security as part of HADOOP-6566,
> DiskChecker#mkdirsWithExistsAndPermissionCheck will return true even if it
> wasn't able to create the directory, which means instead of throwing a
> DiskErrorException the code will proceed to getFileStatus and throw a FNF
> exception. Post HADOOP-7040, which modified makeInstance to catch not just
> DiskErrorExceptions but IOExceptions as well, this is not an issue since now
> the exception is caught either way. But for future modifications we should
> still modify this method to return false if it was unable to create the
> directory. This code is totally different in trunk, so not an issue there.
