> HDFS Space Quota not working as expected
> ----------------------------------------
>
> Key: HDFS-7658
> URL: https://issues.apache.org/jira/browse/HDFS-7658
> Project: Hadoop HDFS
> Issue Type: Bug
> Environment: CDH4.6
> Reporter: Puttaswamy
>
> I am implementing hdfs quota in a cdh4.6 cluster .Hdfs name quota has been
> working properly.But the Hdfs Space quota has not been working as
> expected.i.e,
> I set the space quota of 500MB for a directory say /test-space-quota.
> Then i put a file of 10 Mb into /test-space-quota which worked .Now the space
> available is 480 MB ( 500 - 10*2) where 2 is rep factor.
> Then i put a file of 50Mb into /test-space-quota which worked too as
> expected. Now the space available is 380 MB (480 - 50*2)
> "I am checking the quota left from the command hadoop fs -count -q
> /test-space-quota"
> Then i tried to put a file of 100 Mb . It should since it will just consume
> 200 Mb of space with replication. But when i put that i got an error
> "DataStreamer Exception
> org.apache.hadoop.hdfs.protocol.DSQuotaExceededException: The DiskSpace quota
> of /test is exceeded: quota = 524288000 B = 500 MB but diskspace consumed =
> 662700032 B = 632 MB"
> But the quota says
> hadoop fs -count -q /test-space-quota
> none inf 524288000 398458880 1
> 2 62914560 /test-space-quota
> Could you please help on this?
