Subject [jira] [Commented] (HBASE-11325) Malformed RPC calls can corrupt stores
Date Wed, 11 Jun 2014 04:37:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11325?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14027400#comment-14027400
] 

Esteban Gutierrez commented on HBASE-11325:
-------------------------------------------

Forgot to mention that I had to modify the HFile tool to print the row since the Type in some
cases was not valid. (see /4/ instead of /Put/) in the previous comment.

>             Project: HBase
>          Issue Type: Bug
>          Components: Client, regionserver
>    Affects Versions: 0.94.20
>            Reporter: Esteban Gutierrez
>
> We noticed in a cluster a Region Server that aborted with a DroppedSnapshotException
due an IOException in ScanWildcardColumnTracker when the RS tried to flush the memstore. After
further research it was found that a client was sending corrupt RPCs requests to the RS and
those corrupt requests ended into the stores causing corruption of the memstore itself and
in some cases HFiles.  More details to follow.
