Sakthi commented on HBASE-22172:
--------------------------------
Yes [~elserj] you are right. I am not sure if there is any way we can do this
testing currently via Jenkins. Also I'm not sure if these are the complete of
list of warnings that we might see. Some other type of invocations
(pe,ltt,itbll, other mr jobs, etc) might list out other set of warnings. The
above 250 were hit with hbase shell's mere invocation alone. So this is bad if
we have to try all other possible ways as well to access[thrift, rest] (to list
out all such warnings).

> While running a Java 8 compiled hbase on Java 11 system, I found the
> following warnings being thrown. I think we can add the "--add-opens" flag to
> HBASE_OPTS (if the jdk version is 11) to suppress this warning.
