【原创】大叔问题定位分享（25）ambari metrics collector内置standalone hbase启动失败

ambari metrics collector内置hbase目录位于

/usr/lib/ams-hbase

配置位于

/etc/ams-hbase/conf

通过ruby启动

/usr/lib/ams-hbase/bin/hirb.rb

实际的启动命令为

/usr/lib/ams-hbase/bin/hbase-daemon.sh --config /etc/ams-hbase/conf foreground_start master

但是启动一段时间报错：

java.lang.RuntimeException: Master not initialized after 200000ms

查看日志发现第一个错：

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.

这个错可以忽略，然后是第二个错：

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.

这个可以通过设置hbase.unsafe.stream.capability.enforce=false解决，详见 https://www.cnblogs.com/barneywill/p/10283076.html

最后发现很多warn：

清空hbase.rootdir，hbase.tmp.dir，hbase.zookeeper.property.dataDir这3个目录，同时设置好用户权限，然后重启hbase即可；
