Hello Spark Developers, I have 3 tables that i am reading from HBase and wants to do join transformation and save to Hive Parquet external table. Currently my join is failing with container failed error.
1. Read table A from Hbase with ~17 billion records. 2. repartition on primary key of table A 3. create temp view of table A Dataframe 4. Read table B from HBase with ~4 billion records 5. repartition on primary key of table B 6. create temp view of table B Dataframe 7. Join both view of A and B and create Dataframe C 8. Join Dataframe C with table D 9. coleance(20) to reduce number of file creation on already repartitioned DF. 10. Finally store to external hive table with partition by skey. Any Suggestion or resources you come across please do share suggestions on this to optimize this. Thanks Chetan
