ambari metrics collector內置hbase目錄位於
/usr/lib/ams-hbase
配置位於
/etc/ams-hbase/conf
通過ruby啟動
/usr/lib/ams-hbase/bin/hirb.rb
實際的啟動命令為
/usr/lib/ams-hbase/bin/hbase-daemon.sh --config /etc/ams-hbase/conf foreground_start master
但是啟動一段時間報錯：
java.lang.RuntimeException: Master not initialized after 200000ms

查看日志發現第一個錯：
2019-01-16 16:20:29,295 WARN [StoreOpener-1588230740-1] util.CommonFSUtils: FileSystem doesn't support setStoragePolicy; HDFS-6584, HDFS-9345 not available. This is normal and expected on earlier Hadoop versions.

這個錯可以忽略，然后是第二個錯：
2019-01-17 15:49:08,730 ERROR [Thread-24] 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.

這個可以通過設置hbase.unsafe.stream.capability.enforce=false解決，詳見 https://www.cnblogs.com/barneywill/p/10283076.html

清空hbase.rootdir，hbase.tmp.dir，hbase.zookeeper.property.dataDir這3個目錄，同時設置好用戶權限，然后重啟hbase即可；
