High Availability tests for Prod environment


High Availability tests for Prod environment


Hi All,

We have 2 physical servers in our prod cluster

physical server1 hosts s1 - master node; s2 - edge node; s3 - slavenode

physical server2 hosts s4 - slave node s5 - slave node s6 - masternode

As part of HA, we installed NN in s1 and s6 and DNs in s3,s4,s5 and JNs in s1,s6 and s2

Now, after stopping physical server1 - services in s1, s6 and s2 are stopped.

I could not see HA is maintained for HDFS.

Any help on this?
