u should upgrade to 0.94 as you also had issues with row locks as newer version
had improved miniBatchPut code base.

Thanks Carlos. Do you have any rough estimates on timings on snapshot ? (by
leaving copy)

hi
what's the recommended nodes for NN, hmaster and zk nodes for a larger cluster,
lets say 50-100+
also, what would be the ideal replication factor for larger clusters when u
have 3-4 racks ?

Hi
What can make a region server unbalanced when it comes to space ? (and
possibly requests too).
For example; I have 5 node cluster (replication factor of 3); and in which
all 4 has same size; where as one node is almost double in size for /hbase.
Any help will be appreciated; esp what makes th
ionservers.

Does balancer_switch=true; rebalances any skew in the existing keys or it
only does for all new regions ? The requests seems to be oK across all
servers.

As per the docs, it looks like painless to upgrade from 0.20.3 to 0.90
(only need to run upgrade script if upgrading to 0.92).
http://hbase.apache.org/book/upgrading.html#upgrade0.90
Anyone has experience in upgrading from 0.20 to 0.90 or something similar
with major upgrade ? Do we need to upgrad
What is the best practice to remove a node and add the same node back for
hbase/hadoop ?
Currently in our 10 node cluster; 2 nodes went down (bad disk, so node is
down as its the root volume+data); need to replace the disk and add them
back. Any quick suggestions or pointers to doc for the right p
t; Node goes down.
