hbase 异常，
启动hbase shell后发现没有hmaster
先查看/hbase/logs中的日志
org.apache.hadoop.hbase.master.HMasterCommandLine: Failed to start master
java.lang.RuntimeException: HMaster Aborted
at org.apache.hadoop.hbase.master.HMasterCommandLine.startMaster(HMasterCommandLine.java:160)

查看hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:9000/hbase</value>
</property>
查看hadoop：
打开：http://localhost:50070/
两处的端口不对应，将hbase-site.xml改为
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://localhost:8020/hbase</value>
</property>
