2.以开始以为语法有错误，不会啊，很简单的语法。经过测试几个命令发现，但凡和权限相关的命令，都失败了
百度到一些建议，需要检查参数，在确认下面几个参数都设置正确的情况下，问题依旧
hbase.master.keytab.file
hbase.master.kerberos.principal
hbase.regionserver.keytab.file
hbase.regionserver.kerberos.principal
hbase.coprocessor.master.classes
hbase.coprocessor.region.classes
hbase.security.authorization
3.百度到以下链接，其中有介绍：
参考链接
https://community.hortonworks.com/questions/50984/security-features-not-available-in-hbase-kerberize.html
It seems your hbase:acl table is not created.
can you check hbase-site.xml at master side as well it should have:-
hbase.coprocessor.master.classes
org.apache.hadoop.hbase.security.access.AccessController
try restarting your cluster as postStartMaster step should create this table, once you are able to do scan 'hbase:acl' , you will not see above error "ERROR: DISABLED:Security features are not available"
4.下面这句话，提醒了我，是不是hbase:acl丢失了？
try restarting your cluster as postStartMaster step should create this table, once you are able to do scan 'hbase:acl'
5.一检查，发现真没了
6.正常的情况应该是
7.问题原因找到了，开始找解决办法吧。继续百度（search技术文档，特别怀念google）
如何重建hbase:acl呢？安装过程中hbase并没有任何特殊设置，只要在hdfs上创建一个/hbase目录，启动hbase master就会自动创建需要的文件。为什么重启几次，都没有重新创建这个acl表呢？
查看hbase master log，可以看到错误“The table hbase:acl does not exist in meta but has a znode. run hbck to fix inconsistencies.” 通过命令hbase hbck检查，没有错误。问题也没有解决

确实看到，前面准备赋权，却失败的信息，记录在znode的acl路径下
hbase zkcli
[zk: 192.168.0.72:2181,192.168.0.73:2181,192.168.0.74:2181(CONNECTED) 3] ls /hbase

[@test_user]
9.在zk上删除/hbase的信息，然后重启hbase整个集群，让hbase自动重建acl表
[zk: 192.168.0.72:2181,192.168.0.73:2181,192.168.0.74:2181(CONNECTED) 6] rmr /hbase

10.可以看到，文件已经回来了
[hdfs@testserver ~]$ hdfs dfs -ls /hbase/data/hbase
Found 3 items
drwxrwx--- - hbase hadoop 0 2018-02-24 17:00 /hbase/data/hbase/acl

drwxrwx--- - hbase hadoop 0 2018-02-24 17:00 /hbase/data/hbase/namespace
11.acl表也可以查看了
hbase(main):004:0> scan 'hbase:acl'
ROW COLUMN+CELL
test_table column=l:hbase, timestamp=1519463374193, value=RWXCA
test_table_01 column=l:hbase, timestamp=1519463409831, value=RWXCA
user_01 column=l:hbase, timestamp=1519463393177, value=RWXCA
3 row(s) in 0.1600 seconds
遇到问题，在理解整体架构原理的情况下，有目的，有范围的一步步检查，终归是可以解决的。
