Maksym Rymar commented on DRILL-8321:
-------------------------------------
[~pj.fanning] Yes, I was thinking about this too. One way is to replace
[https://github.com/phatak-dev/java-sizeof] with
[https://github.com/DimitrisAndreou/memory-measurer] or even with a fork from
the last written on a pure java 8 [https://github.com/shihyuho/memory-measurer]
. Another way is to try to implement something own, as this library is used
only for one special place.
> Change kafka_2.13 dependency scope to test
> -------------------------------------------
>
> Key: DRILL-8321
> URL: https://issues.apache.org/jira/browse/DRILL-8321
> Project: Apache Drill
> Issue Type: Task
> Affects Versions: 1.20.2
> Reporter: Maksym Rymar
> Assignee: Maksym Rymar
> Priority: Minor
> Fix For: 1.20.3
>
>
> Drill has 2 scala dependencies:
> * {{org.apache.kafka.kafka_2.13}}
> * {{com.madhukaraphatak.java-sizeof_2.11}}
> which are targets on different scala versions 2.13 and 2.11. But Scala has no
> backward compatibility for major releases, so we can’t have 2 libraries
> compiled on various versions of scala.
> To solve the issue there are only 2 ways:
> # Compile both libraries on the same major Scala version.
> # Remove one of the libraries from Drill
> {{kafka_2.13}} is server side (kafka’s server side) dependency and is
> unnecessary on the client side (Drill). Probably, it was added carelessly to
> Drill to a compile scope, while it is necessary only in a test scope.
> So {{kafka_2.13}} can be removed from compile scope. It will reduce the Drill
> package size and the main – it will solve scala version conflict.
