Hi all,
If I want to add a new Keyspace, does it mean I have to distribute my
storage-conf.xml to whole nodes? and restart whole nodes?

Sorry, typo in mail adddress.
Hi all,
I run my performance testing in random read, but I got the
hfile.block.cache.size = 0 performance is better than default, Is it
possible?
My cluster (4 nodes):
Hadoop 0.20.2, HBase 0.20.6
1 * namenode & hmaster & zookeeper
3 * datanode & regionserver
P.S. Replication factor = 3, H
Yes, only 14.7% :-(

Hi all,
I encounter a problem about long gc pause cause the region server's local
zookeeper client cannot send heartbeats, the session times out.
But I want to know why the HBase master sends a MSG_REGIONSERVER_STOP op to
region sever to stop its services rather than reinitialize a new zookeepe
Hi St.Ack,
Please see the attach file, and there are 3 RS/DN/TT + 1 MS/NN/JT in my
cluster. (Hadoop-0.20.2, HBase 0.20.6)
Thanks.

Hi all,

Thanks.
