全网最详细的启动zkfc进程时，出现INFO zookeeper.ClientCnxn: Opening socket connection to server***/192.168.80.151:2181. Will not attempt to authenticate using SASL (unknown error)解决办法（图文详解）
不多说，直接上干货！

解决办法：
注意：之前，先得启动好，每台机器的zookeeper进程。
有时候，还不一定，管用。
最好，是先如下执行才能解决。
[zk: localhost:2181(CONNECTED) 0]
[zk: localhost:2181(CONNECTED) 0] ls /
[kfk, hbase, hadoop-ha, admin, zookeeper, consumers, config, rmstore, yarn-leader-election, brokers, controller_epoch]
[zk: localhost:2181(CONNECTED) 1] rmr /hadoop-ha
[zk: localhost:2181(CONNECTED) 2]
再执行，
[kfk@bigdata-pro01 ~]$ cd /opt/modules/hadoop-2.6./
[kfk@bigdata-pro01 hadoop-2.6.]$ cd bin/
[kfk@bigdata-pro01 bin]$ ./hdfs zkfc -formatZK
[kfk@bigdata-pro01 zookeeper-3.4.-cdh5.10.0]$ cd
[kfk@bigdata-pro01 ~]$ cd /opt/modules/hadoop-2.6./
[kfk@bigdata-pro01 hadoop-2.6.]$ cd bin/
[kfk@bigdata-pro01 bin]$ ./hdfs zkfc -formatZK
