[jira] [Created] (DRILL-8257) Resolve Netty lib conflicts

James Turton created DRILL-8257:
-----------------------------------

             Summary: Resolve Netty lib conflicts
                 Key: DRILL-8257
                 URL: https://issues.apache.org/jira/browse/DRILL-8257
             Project: Apache Drill
          Issue Type: Bug
          Components: library
    Affects Versions: 1.20.1
            Reporter: James Turton
            Assignee: James Turton
             Fix For: 1.20.2


The following transitive dependencies conflict with Drill's own Netty dependencies and need to be excluded.

jars/3rdparty/netty-transport-native-epoll-4.1.45.Final.jar
jars/3rdparty/netty-all-4.1.59.Final.jar
jars/3rdparty/netty-codec-http-4.1.59.Final.jar

It is not understood what exact conditions are needed for the library conflict to adversely affect a Drillbit, but when they are present it becomes impossible to enable TLS on the user RPC port. One guess is that a class loader race condition decides whether the problem will manifest.
