writing to hive is not working
Anusha Buchireddygari created SPARK-26828:
---------------------------------------------
Summary: Coalesce to reduce partitions before writing to hive is not working
Key: SPARK-26828
URL: https://issues.apache.org/jira/browse/SPARK-26828
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.3.0
Reporter: Anusha Buchireddygari
final_store.coalesce(5).write.mode("overwrite").insertInto("database.tablename",overwrite = True), this statement is not merging partitions. I've setÂ
.config("spark.default.parallelism", "2000") \
.config("spark.sql.shuffle.partitions", "2000") \
however repartition is working but takes 20-25 minutes to insert.
