Subject [jira] [Commented] (SPARK-6305) Add support for log4j 2.x to Spark
Date Wed, 18 May 2016 18:25:12 GMT


Sean Owen commented on SPARK-6305:

Although I agree with the general big problem of dependency leakage, I am not sure if this
is an instance. Spark has to interact with some specific logging framework in order to control
logging levels. Otherwise this would be trivial. That aside, I think logging dependencies
are so ubiquitous from third-party dependencies that, Spark or no, any downstream consumer
probably has to deal with excluding something. log4j 1.x is one of the least problematic choices
to make.

I don't think an epic would help, but, talking about shading particular dependencies would.
What do you have in mind? in many cases there are sad stories about why it won't help. Why
is shading a bad thing?

Since there are shaded jars, it must be done during the build.
