Subject Base can't start due to Zookeeper
Date Tue, 21 Apr 2015 18:38:41 GMT
Hi,

I’m a beginner of HBase. I’m recently deploying HBase 1.0.0 onto Emulab using Hadoop 2.6.0
When I type bin/start-hbase.sh, Hbase and HRegionservers starts and then shut down. The master
log are as follows:

My Hbase-site.xml is:

  </property>

    <name>hbase.zookeeper.property.dataDir</name>
    <value>/proj/ucare/bo/hadoop_data/zookeeper</value>

    <value>pc440.emulab.net<http://pc440.emulab.net>,pc439.emulab.net<http://pc439.emulab.net></value>
    <description>The directory shared by RegionServers.

    <value>true</value>
  </property>
  <property>
    <name>dfs.replication</name>
    <value>1</value>
  </property>
</configuration>

The regionservers file is:

BF@pc440.emulab.net<mailto:BF@pc440.emulab.net>
BF@pc439.emulab.net<mailto:BF@pc439.emulab.net>

Someone could tell me how to fix it?

Thanks a lot!

Bo
