Full network most detailed start or format ZKFC when the Java.net.NoRouteToHostException:No route to host appears ... Attempt to authenticate using SASL (unknown error) error resolution (text)

Not much to say, directly on the dry goods!

Workaround:

Each machine is executed first ,sudo chkconfig iptables off

Again, execute

[Email protected] hadoop-2.6. 0] $ sbin/hadoop-/opt/modules/hadoop-2.6. 0/logs/hadoop-kfk-zkfc-bigdata-pro01.kfk.com.  out [email protected]-pro01 hadoop-2.6. 0 ]$ JPS7320  JPS7285  dfszkfailovercontroller[[email protected]- Pro01 hadoop-2.6. 0

Sometimes, not necessarily, it works.

To be resolved as follows.

[Zk:localhost:21810] [zk:localhost:21810] ls/[KFK, HBase, Hadoop -ha, admin, zookeeper, consumers, config, Rmstore, yarn-leader-election, brokers, CONTROLLER_EPOCH][ZK: localhost:21811] rmr/hadoop-ha[zk:localhost:21812

Then, restart ZKFC or format ZKFC.
