-----------------------------------
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.
