[jira] [Commented] (SPARK-26828) Coalesce to reduce partitions
before writing to hive is not working
[ https://issues.apache.org/jira/browse/SPARK-26828?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16762436#comment-16762436 ]
Hyukjin Kwon commented on SPARK-26828:
--------------------------------------
Can you make a self-reproducer so that people can deduplicate the efforts to investigate this? Also, I wonder if {{spark.default.parallelism}} and {{spark.sql.shuffle.partitions}} matter.

> final_store.coalesce(5).write.mode("overwrite").insertInto("database.tablename",overwrite = True), this statement is not merging partitions. I've setÂ
