Subject [jira] Commented: (HBASE-2519) StoreFileScanner.seek swallows IOEs
Date Fri, 07 May 2010 08:06:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12865070#action_12865070
] 

Todd Lipcon commented on HBASE-2519:
------------------------------------

In fact this needs to bubble all the way through to client - right now we also silently return
no rows in a scanner in ScannerCallable on the client side if we get an IOE that isn't a DoNotRetryIOException
or NSRE.

> If a storefilescanner fails to seek, it silently swallows the IOE and returns false as
if it were the end of the scanner.
> This means that we can silently lose data if an IOE occurs for one of the store files
during a compaction.
