CHECK ZOOKEEPER fails on install,start and test step

CHECK ZOOKEEPER fails on install,start and test step

New Contributor

Hello,

I am getting error on CHECK ZOOKEEPER step during installation/deployment of my 5 node cluster.

when I proceed further, It shows many services has not started. Although when I start them manually, All services get up.
The problem occurs only once i.e., first time only during installation/deployment of cluster.

NOTE:- I am using zookeeper 3.4.14 version.

here is my stderr on respective node.

Traceback (most recent call last):
