I am performing spark action with oozie but I have some doubts over for spark :

  1. what is oozie.action.sharelib.for.spark

as I could see in examples its value is set to spark2 , is it like value of this present location of jar files needed to run the job.

2. what if I skip this filed in oozie.use.system.libpath=true

or what is impact if I set its value true in the file.

3. what does oozie.libpath present ? is value of this field is location of all jar files needed for running the job with spark2 , if yes

then do we need oozie.action.sharelib.for.spark filed in the library ? or what if we set both

Thanks in advance
