Hi all,
I have problem starting a cluster of 1 master and 3 region server. When I
started the cluster, the HMaster and HRegionserver will automatically exit.
My abase-site.xml:
<configuration>
<property>
<name>hbase.master</name>
<value>hadoopmaster:60000</value>
</property>
<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoopmaster:9000/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>

Can someone helps me figure out the problem? Is that because the number of
region server and zookeeper nodes are incorrect?
Thanks a lot!
