Thank you Mike, I'm looking forward this fix. I hope the problem won't
impact us very much, as it didn't so far.

This is a known bug and is fixed in 90.2. Cloudera's CDH3B4 is 90.1.
They are aware of this issue and if it impacts you, you may want to ask them to
raise its priority for Todd L. to back port the fix.
(Now Todd is going to hate me for making him do more work :-) )

Hi,
I have come across the exact same issue a while ago. I am no expert but it
seems balancer is not reassigning newly split regions, in order to reduce
client disconnect problems, selecting other regions on the RS instead. I
have seen a JIRA about this behaviour but i can't remember the id. Anyways,
this is not a real solution but i overcame it by disabling unused tables.
Still, i too am curious about some expert opinion.

Hi all,
We are using ASF HBase 0.90 with cloudera distribution for HDFS(cdh3b3)).
We have a cluster with 6 machines 1135 regions on each machine.
We have many tables, each of them having regions on many nodes. We've
created a new table and started to load it. The other tables are not used
anymore. The problem is that all regions of the new table are on the same
machine(about 150 regions) and it is really loaded! The entire cluster is
still well distributed (the same number of regions on each machine), but it
seems that only old tables are redistributed. Also, the table's data is
distributed in HDFS across the entire cluster.
Do you have any idea what is wrong with it?
Thank you,
Iulia
