Puttaswamy created HADOOP-11503: ----------------------------------- 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? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
