Hi
We are using elasticsearch 7.3.2 version with java 8 and with the tcp client we are accessing the cluster from the java application running with java 17

is there any issue in this

Not really.

But, this server version is old and you should definitely upgrade to the latest 7.17.

Hi David Pilato,

we are working on the rolling upgrade from 7.3.2 to 7.17

my question is - we are using 7.14 version elasticsearch client library, that is compatible with ES 7.3.2 and application java 17 right ?

It should be. The recommendation is still to use the same version everywhere but this should work.

Note that the Java client changed recently. So I'd look at the new one as it's a bit different than the previous one and specifically it brings much lesser dependencies than the high level rest client.
