In HDP3, I am trying to ingest DB and File copy using PySaprk. After the job completion hive db is not listed in hive cli. After checking the property in Ambari came to know there is spark warehouse directory where all the hive tables are created and it is not listed under hive databases.
So i changed above property to hive warehouse
After changing the spark warehouse property i rerun the spark job and tried to list from hive-cli show databases, no luck. When i tried to check the hdfs location /warehouse/tablespace/managed/hive i can see all the db names are created as.db files.
how to resolve this issue, Please help.
you need to use hive warehouse connector to connect hive databases from HDP3 on words.

@subhash parise - Thanks for the answer..
as mentioned in the url https://docs.hortonworks.com/HDPDocuments/HDP3/HDP-3.1.0/integrating-hive/content/hive_hivewarehouse... I have added custom spark2-default properties and rerun the jobs and the job succeeded but i am not seeing any databases created from hive-cli show databases..
