-----------------------------------
Summary: HDFS Space Quota not working as expected
Key: HADOOP-11503
URL: https://issues.apache.org/jira/browse/HADOOP-11503
Project: Hadoop Common
Issue Type: Bug
Components: fs
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?
