我正在使用Hadoop2.4.0 / Hbase 0.98.0 / Hive 0.14.0
Hadoop和HBase运行良好，直到我重新启动我的HMaster。 hbase-hduser-master-master.log文件中出现以下错误：

这里有什么问题以及HMaster Aborted意味着什么？
了解更多信息，这就是我hbase-site.xml的样子：

答案 0 :(得分：9)
我今天遇到了这个问题！我的解决方案如下：
第1步：停止Hbase。
第2步：运行以下命令
hbase org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair
此命令用于修复Hbase的MetaData
步骤3：删除zookeeper中的数据（警告它会让你丢失旧数据）
./opt/cloudera/parcels/CDH-5.1.0-1.cdh5.1.0.p0.53/lib/zookeeper/bin/zkCli.sh
您可以使用ls /扫描zookeeper中的数据
使用rmr /hbase删除zookeeper中的hbase数据
第4步：启动hbase
答案 1 :(得分：5)
这是基于另一个答案，但要澄清升级cloudera 5.4
第1步：
service hbase-regionserver stop
service hbase-master stop
第2步：
hbase org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair
步骤3：删除zookeeper中的数据（警告它会让你丢失旧数据）
cd /usr/lib/zookeeper/bin/
./zkCli.sh
它打开了zookeeper shell。
然后运行：
ls /
rmr /hbase
第4步：启动hbase
service hbase-master restart
service hbase-regionserver restart
