Jakob Homan commented on HDFS-740:
----------------------------------
A quick instrumentation of code and Gary able to prove mkdir is throwing an
exception, but it's an odd one:
{noformat}
an IOException from mkdirs:
org.apache.hadoop.hdfs.protocol.DSQuotaExceededException: The DiskSpace quota
of /user/hadoopqa is exceeded: quota=1 diskspace consumed=19.6g
{noformat}
I didn't think that creating a directory would count against your DSQuota.
Still poking around.
At the very least this code should be fixed no to silently catch the exception.
After Boris' fix (HADOOP-6203), the log message at least indicates there was
an exception rather than a false return value, but still swallows the exception
and doesn't log what it actually was.
> rm and rmr fail to correctly move the user's files to the trash prior to
> deleting when they are over quota.
