Fixing issues with Impala Virtual Warehouse

After an HDFS NameNode migration on a Cloudera Base on premises instance, the Hive Virtual Warehouse can go down and become inoperable. Learn how to fix issues with your Impala Virtual Warehouse.

Like in the case of Database Catalog and Hive Virtual Warehouse, you do not have the option to modify the hadoop-hdfs-site configuraton file in an Impala Virtual Warehouse. Therefore, the only way to fix this issue is to delete the Virtual Warehouse and recreate it with the same name, configuration, autoscaling parameters, user groups, and so on.
