I have run the job in cluster mode as well. The job is not ending. After
sometime the container just do nothing but it shows running.

In my code, every record has been inserted into solr and cassandra as well.
When i ran it only for solr the job completed successfully. Still i did not
test cassandra part. Will check and update.

does anyone have faced this issue earlier.

I added sparsession.stop after foreachpartition ends.

My code overview:

read parquet file(20 partition- roughly 90k records)
          every record do some compution
          insert into cassandra(  i am using insert command )
         index into solr

stop the sparksession
exit the code.
