DWX-15571: tez.history.logging.proto-base-dir and hive.hook.proto.base-directory locations change after the runtime upgrade

The values of following Hue Query Processor properties change after you upgrade the Database Catalog and Virtual Warehouses to the latest version:

tez.history.logging.proto-base-dir
hive.hook.proto.base-directory

CDW changes these locations to match the base cluster configuration for hive.metastore.warehouse.external.dir. You may also see the FileNotFoundException: File does not exist error in the Hue Query Processor logs.

To use the old location and to avoid seeing the "File does not exist" error in the logs, you must update the Hue Query Processor configurations as follows:

Log in to the Data Warehouse service as an DWAdmin.
Go to Database Catalog > > Edit > CONFIGURATIONS > Hue query processor and select hue-query-processor.json from the Configuration files drop-down menu.
Note the paths of the tez.history.logging.proto-base-dir and hive.hook.proto.base-directory properties.
After you upgrade the Database Catalog, go to Database Catalog > > Edit > CONFIGURATIONS > Hue query processor and select hue-query-processor.json from the Configuration files drop-down menu.

Specify the desired path under the dasConf section as shown in the following example:

  "dasConf": {
    "hive.hook.proto.base-directory": "/warehouse/tablespace/external/hive/sys.db/query_data",
    "tez.history.logging.proto-base-dir": "/warehouse/tablespace/external/hive/sys.db"
  },
