Subject [jira] [Updated] (HDFS-7349) Support DFS command for the EC encoding
Date Fri, 10 Apr 2015 11:32:13 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7349?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinayakumar B updated HDFS-7349:
--------------------------------
    Attachment: HDFS-7349-003.patch

Updated the patch.
Now only following commands are added.
{noformat}Usage: hdfs ec [generic options]
	[-createZone -s <schemaName> <path>]
	[-getZoneInfo <path>]
	[-help [cmd ...]]
	[-usage [cmd ...]]
{noformat}

For the convertion of the existing files, definite symantics have not been discussed yet.
Once those are finalized we can add them in followup jiras.

For the clean apply, patch depends on HDFS-8122's latest patch.
Please review the patch and provide your comments.
-Thanks
