[jira] [Commented] (HBASE-3722) A lot of data is lost when name
node crashed
[ https://issues.apache.org/jira/browse/HBASE-3722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13016208#comment-13016208 ]
gaojinchao commented on HBASE-3722:
-----------------------------------
Jean-Daniel answers in mail as:
MasterFileSystem has most of DFS interactions, it seems that checkFileSystem is never called (it should be) and splitLog catches the ERROR when splitting but doesn't abort.
Would you mind opening a jira about this issue and perhaps submit a patch?
when will it submit a patch and I want to test it?
thanks.
