[SPARK-19026]SPARK_LOCAL_DIRS(multiple directories on different disks)
cannot be deleted
JIRA Issue: https://issues.apache.org/jira/browse/SPARK-19026
SPARK_LOCAL_DIRS (Standalone) can be a comma-separated list of multiple
directories on different disks, e.g. SPARK_LOCAL_DIRS=/dir1,/dir2,/dir3, if
there is a IOExecption when create sub directory on dir3 , then the sub
directory which have been created successfully on dir1 and dir2 cannot be
deleted anymore when the application finishes.
So we should catch the IOExecption at Utils.createDirectory , otherwise
the variable "appDirectories(appId)" which the function maybeCleanupApplication
calls will not be set . If the number of folders "executor-**" > 32k(ext3) then
we cannot create any executor on this worker node.
