Subject [jira] [Commented] (HDFS-7349) Support DFS command for the EC encoding
Date Tue, 14 Apr 2015 05:16:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14493583#comment-14493583
] 

Kai Zheng commented on HDFS-7349:
---------------------------------

2. In {{CreateECZoneCommand}}, it could report "doesnot match any of the supported schemas".
Note a typo here.
3. Would we add a new command for user to list all the available schemas? This is necessary
before the user creates a zone and needs a schema.
