HBase master.HMaster: Failed to become active master
报错内容：
ERROR [master/h136:16000:becomeActiveMaster] master.HMaster: Failed to become active master
java.lang.IllegalStateException: The procedure WAL relies on the ability to hsync for proper operation during component failures, but the underlying filesystem does not support doing so. Please check the config value of 'hbase.procedure.store.wal.use.hsync' to set the desired level of robustness and ensure the config value of 'hbase.wal.dir' points to a FileSystem mount that can provide it.

解决方法：
在配置文件 hbase-site.xml 中添加：
<property> <name>hbase.unsafe.stream.capability.enforce</name> <value>false</value> </property>
