Subject [jira] [Commented] (HBASE-6516) hbck cannot detect any IOException while ".tableinfo" file is missing
Date Fri, 31 Aug 2012 15:29:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6516?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13446049#comment-13446049

Jonathan Hsieh commented on HBASE-6516:

Can you test these to see if they hang?  We've touched a few places and we need to dig into
code to see if they are related.  The TestHBaseFsck one is a little concerning since we modified

> HBaseFsck checks those missing .tableinfo files in loadHdfsRegionInfos() function. However,
no IoException will be catched while .tableinfo is missing, since "FSTableDescriptors.getTableDescriptor"
doesn't throw any IoException.
