CDH4.4 tarball hbase 配置錯誤 FATAL org.apache.hadoop.hbase.master.HMaster: Unhandled exception.

本人根據cloudera官網配置cdh4.4 的hbase：

http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Installation-Guide/cdh4ig_topic_20_5.html

打算啟動集群時Hmaster會自動死掉，log顯示錯誤如下：

在網上找了一下午，原來把./hbase-0.20.3/conf/hbase-site.xml中
<name>hbase.rootdir</name>
<value>hdfs://master:9900/hbase</value>
和
./hadoop-2.0.0/etc/hadoop/core-site.xml中
<name>fs.default.name</name>
<value>hdfs://master:9900/</value>
保持一致就可以了。
