Subject RE: openjdk for cassandra production cluster
Date Wed, 10 Oct 2018 15:09:50 GMT
I’m using OpenJDK on version 3.10 (rehl 7.3) in Production and have the warning in the logs.
I have a stable system, I think you can ignore it.

The warning should be removed (if it hasn’t already), it’s unnecessary at this point

HI users,
I have created a cassandra cluster with openjdk 1.8.0_181 version.(cassandra 2.1.17)
started each node, cluster looks healthy,but in  the log files saw the WARN
message below:

WARN [main] 2014-01-28 06:02:17,861 (line 155) OpenJDK
is not recommended. Please upgrade to the newest Oracle Java release

Is this message  WARN informational only or can it be real issue?
Did any one noticed something like this (Or using openjdk for production environment)

Thanks ,
Jon Haddad<>
