Parth Chandra commented on DRILL-5568:

In the functional test framework build, this change is causing the  size of the jdbc-all jar
file to bloat and thebuild fails with the error:

  drill-jdbc-all-1.11.0-SNAPSHOT.jar size (78517001) too large. Max. is 29000000

> With Sasl support in 1.10 the authentication using username/password was moved to Plain
Mechanism of Sasl Framework. There are couple of Hadoop classes like Configuration.java and
UserGroupInformation.java defined in hadoop-common package which were used in DrillClient
for security mechanisms like Plain/Kerberos mechanisms. Due to this we need to add hadoop
dependency inside _drill-jdbc-all.jar_  Without it the application using this driver will
fail to connect to Drill with authentication enabled.
> Today this jar (which is JDBC driver for Drill) already has lots of other dependencies
which DrillClient relies on like Netty, etc. But the way we add these dependencies are under
*oadd* namespace so that the application using this driver won't end up in conflict with it's
own version of same dependencies. As part of this JIRA it will include hadoop-common dependencies
under same namespace. This will allow an application to connect to Drill using this driver
with security enabled.
