Verifying Hive data migration
After the replication policy runs successfully, you can view the replication job status on the Replication Policies page.
An administrator can verify whether the job starts and runs as expected using the following steps:
- For HDFS data replication, check the cloud storage path (S3 bucket path) to verify whether the data was successfully copied in the specified bucket.
- For Hive metadata replication, verify whether the specified source database, along with tables, partitions, UDFs, and column stats are available in the Data Lake HMS instance. For this, the administrator can use a Data Hub cluster and run the corresponding queries using Hue or beeline.
- For Ranger policies, query the Ranger policies to ensure that the Sentry policies are properly mapped as Ranger policies for the right users and groups.
