[jira] [Commented] (DRILL-7494) Unable to connect to Drill using JDBC driver when using custom authenticator

["Vova Vysotskyi (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-7494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17001224#comment-17001224 ] 

Vova Vysotskyi commented on DRILL-7494:
---------------------------------------

Another issue caused by the Hadoop upgrade is the problem with a Guava version mismatch. Moving back {{woodstox-core}} is not enough, the application hangs due to {{MethodNotFoundException}} in {{Preconditions}} class. Patching may be done in {{org.apache.drill.jdbc.Driver}} class, but it doesn't work as expected for the case of some class loaders, for example, it wouldn't work for SquirreLSql.

Some time is required to find a way how to fix this limitation.

>    Affects Versions: 1.17.0
>            Reporter: Vova Vysotskyi

> Steps to reproduce:
> Set up Drill with a custom authenticator as described here: https://drill.apache.org/docs/creating-custom-authenticators/
> Try to connect using simple java client.
> Connection hangs without any errors. It is caused by the fix for DRILL-6540 where was excluded {{com.fasterxml.woodstox:woodstox-core}} but its classes are used in {{org.apache.hadoop.conf.Configuration}}.
