Hi, HBaser
I'm currently trying to run HBase, but some errors occur.
Running environment:
CentOS release 5.5
hadoop-0.20.2
hbase-0.20.6
I use two machines to run hbase (just for illustrate this issue).
Master is : 192.168.22.18 /192.168.25.18
RegionServer is : 192.168.22.19 /192.168.25.19
In my cluster, every machine has dual NIC. Maybe that's the problem, I
guess...
~~~~~~~
In hbase-site.xml, list some configurations
<property>
<name>hbase.zookeeper.quorum</name>
<value>192.168.25.18, 192.168.25.19</value>
...
</property>
After run the start-hbase.sh, these relevant processes have been started!
Run "hbase shell" to excute some commands:
--------------------------------------------------------
hbase(main):002:0> create "table1","cf1"

And then execute "zk_dump", gets infomation as follows:
