openjdk for cassandra production cluster
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 CassandraDaemon.java (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 ,
Prachi

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
