Subject [jira] [Commented] (HBASE-11136) Add permission check to roll WAL writer
Date Tue, 09 Sep 2014 03:40:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11136?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14126541#comment-14126541

Enis Soztutar commented on HBASE-11136:

This looks important to fix. 

postRollWALWriter() is not called from the RS. Also the name pre/postRollWALWriter() implies
that they are called from RS normally (for all WAL rolling), but these are just for log roll
requests. we should name them postRollWALWriterRequest() I think. 

Other than that, the patch looks good. [~apurtell] it would be good if you took a look.

>    Affects Versions: 0.96.2, 0.98.2
>            Reporter: Jerry He

>            Priority: Minor
>             Fix For: 0.99.0

> Currently HBase provides HBaseAdmin.rollHLogWriter() and shell command to roll WAL on
a region server. But no permission check is done on this operation in a secure cluster.
> We need to add permission check to prevent un-authorized user from running this operation.
