In apache Drill Client 1.17, Netty version 4.0.48.Final is being used and it suffers from vulnerability (CVE-2019-16869):
This has been fixed in the latest netty (4.1.50.Final).
We want to build a drill with the latest Netty version that is free from any vulnerabilities.
As there are many breaking changes from 4.0.48 to 4.1.50, I have modified the code accordingly.
I noticed that after trying to upgrade the dependency, I was unable to connect with SSL enabled.
Connecting to the server timed out. This is sometimes due to a mismatch in the SSL configuration between client and server. [ Exception: Waited 10000 milliseconds for org.apache.drill.shaded.guava.com.google.common.util.concurrent.SettableFuture@6ea2bc93[status=PENDING]].
I have created a pull request containing the changes which I have tried to make.
Could someone please advise further on what needs to be changed?
