Hi Stack,
finally the migration worked. We copied table data from 0.20.4 hbase cloud
to cdh3u1 cloud (0.90.3 hbase) by using the mozilla approach to copying the
files on hdfs level. (

OK. So the daughters and parents are all 'online'.

Hi Stack,
the scan of META does not contain any 'offline' or 'split' attributes. Still
parent reqion is present in META. I tried to merge the parent with one child
but received the following error: (on 0.90.3)

Hi Stack,
looking at the old 0.20.4 cluster the parent region is not written to any
more. (no data on filesystem) In META table I can not identify that this
parent region is offlined though. Where can I find that key? Why is the
region not being written to any more if there is no offline flag set?

Hello,
I am wondering what the best way is to fix errors reported with hbck in
0.90.3.
We did a migration from 0.20.4 to 0.90.3 by copying over hbase tables from
0.20.4 to a new cluster with 0.90.3. Then we used add_table.rb to create
META table from scratch. (we stopped all writes to source clust
Hi Marc,
Can you give some clues/links about how to manipulate the .META.
in details? For example, how to build an encoded region name, for
filling up the holes in .META., and how to assign the hole region then
compact it. Finally, I also tried check_meta.rb, it does not work for me.
Any suggestio

We have resolved the issue. Details follow as "lessons learned".
Yes, Stack, the info:splitA/B columns followed, as part of the offline'd
parents .META. row. But the regions that splitA/B point to *did not
exist*in .META.
Also, after the original email, we checked in HDFS and found the parent

So, yeah Marc, what are the rows that follow the ones you post below?
Are they the info:splitA and info:splitB or something else?

Are the daughter regions in the meta table? Are both there? Are they both
online?
You could try enabling the parent region

We had an issue a day ago with some OOME's on the region servers. The
master shutdown ok, but most of the RegionServers didn't and so eventually
had to kill -9 them. Brought it all back up and ran a major compaction to
change the hbase block size. This seemed to work, but now we have an
