问题:HBase master 立即下线

由于磁盘空间问题,我的 hadoop 服务器已关闭,然后我们增加了磁盘空间,然后 HDFS、zookeeper、kafka 开始工作,但 HBase 无法正常工作。

从 Ambari 重新启动 Hbase 时抛出异常。

org.apache.hadoop.hbase.util.FileSystemVersionException: HBase file layout needs to be upgraded. You have version null and I want version 8. Consult http://hbase.apache.org/book.html for further information about upgrading HBase. Is your hbase.rootdir valid? If so, you may need to run 'hbase hbck -fixVersionFile'.

根据我以 hbase 用户身份运行命令hbase hbck -fixVersionFile的建议,然后我收到如下错误:

我正在运行一个由三个节点组成的集群。当我检查 hbase.root.dir hbase.version 文件时不存在。

HbaseVersion -2.0.2
zookeeper - 3.4.6

解答

我包含了来自另一台服务器的 hbase 版本文件。现在它工作正常。
