1、HBase Master启动失败 报 master.HMaster: Failed to become active master 解决方法

报错内容：

ERROR [Thread-21] 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：

hbase.zookeeper.quorum
cbp4.chinaoly.com,cbp3.chinaoly.com,cbp2.chinaoly.com



hbase.zookeeper.property.dataDir
/home/hadoop/data/zookeeper/zkdata



hbase.zookeeper.property.clientPort
2281



hbase.rootdir
hdfs://hadoop3cluster/hbase



hbase.cluster.distributed
true



hbase.unsafe.stream.capability.enforce
false

添加方框配置
