Subject [jira] [Commented] (HBASE-4301) META migration from 0.90 to trunk fails
Date Fri, 02 Sep 2011 07:16:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13095832#comment-13095832

Ted Yu commented on HBASE-4301:
-------------------------------

@Sebastian:
Thanks for your investigation.

You may have noticed the following method in FSUtils:
{code}
  public static HTableDescriptor getTableDescriptor(FileSystem fs, Path tableDir)
{code}
which calls hTableDescriptor.readFields().
You can write a short standalone program utilizing FSUtils.getTableDescriptor() to analyze
what is inside .tableinfo for .META. table.

If you don't time for the above action, please attach log snippet showing more details around
TableNotFoundException. The log Todd posted doesn't give me much clue.

> I started a trunk cluster as an upgrade from 0.90.4ish, and now my META table is screwed.
I can't scan it, etc, and other operations fail.
