Just FYI: I've just tested the redundancy of region servers on a Hadoop
0.20.2/HBase 0.20.6, with 2 region servers. The results are: it works fine, only

Could you kindly suggest, how to make HBase redundant, so that all tables are
available even if one of region servers fails/dies?
Have I missed a Hadoop/HBase setting to do so?
Thank you,

Hello All,
In my Hadoop 0.20.1/HBase 0.20.3/Zookeeper 3.2.2 installation, which is running
on only one node in a pseudo-distributed mode, I noticed, Zookeeper claims to
know 11 nodes (see 'Node count' below). How could it be?
HBase tree in ZooKeeper is rooted at /hbase

Yes, I'm running a transactional hbase.
Thanks in advance for involving any of transactional experts.

Dear experts,
Could you kindly suggest, how to help the RegionServer to complete
initialization in the following situation:
After a failure of one or RegionServers, which is running on a dedicated node in
a HBase/Hadoop cluster (HBase v.0.20.3), the RegionServer can't initialize
available tables.
