Ted Yu commented on HBASE-4301:
-------------------------------
As I mentioned earlier, the table name for .META. HRI was empty. See contents
of ROOT table:
{code}
.META.,,1
column=info:regioninfo, timestamp=1314743864747, value=REGION => {NAME =>
'.META.,,1', TableName =
> '', STARTKEY => '', ENDKEY => '', ENCODED
=> 1028785192,}
{code}
Patch version 3 solves the problem.
I was able to browse the tables in Master UI after migration.
We still need to fill out tablename for .META. in ROOT table.
> META migration from 0.90 to trunk fails
