Apache Spark reassigned SPARK-31432:

> Make SPARK_JARS_DIR configurable
> --------------------------------
>                 Key: SPARK-31432
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: Deploy
>    Affects Versions: 3.1.0
>            Reporter: Shingo Furuyama
>            Priority: Minor
> In the script under bin/sbin, it is better that we can specify SPARK_JARS_DIR as same
> Our usecase:
>  We are trying to employ spark 2.4.5 with YARN in HDP2.6.4. Since there is an incompatible
conflict on commons-lang3 between spark 2.4.5 and HDP2.6.4, we tweak the jars by Maven Shade
>  The jars slightly differ from jars in spark 2.4.5, and we locate it in a directory different
from the default. So it is useful for us if we can set SPARK_JARS_DIR for bin/sbin scripts
to point the direcotry.
>  We can do that without the modification by deploying spark home as many as set of jars,
but it is somehow redundant.
> Common usecase:
>  I believe there is a similer usecase. For example, deploying spark built for scala 2.11
and 2.12 in a machine and switch jars location by setting SPARK_JARS_DIR.
