[jira] Updated: (HADOOP-1180) NNbench test should be able to test the checksumfilesystem as well as the raw filesystem

     [ https://issues.apache.org/jira/browse/HADOOP-1180?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

dhruba borthakur updated HADOOP-1180:
-------------------------------------

    Attachment: nnbench.patch

The default behaviour of the nnbench benchmark is to measure a file system without checksum. If the "-useChecksum" option is specified, then it measures performance with checksums switched on.
