DWX-8460: Unable to delete, move, or rename directories within the S3 bucket from Hue

Problem: You may not be able to rename, move, or delete directories within your S3 bucket from the Hue web interface. This is because of an underlying issue, which will be fixed in a future release.

Workaround: You can move, rename, or delete a directory using the HDFS commands as follows:

SSH into your CDP environment host.
To delete a directory within your S3 bucket, run the following command:
```
hdfs dfs -rm -r [***COMPLETE-PATH-TO-S3-BUCKET***]/[***DIRECTORY-NAME***]
```

To rename a folder, create a new directory and run the following command to move files from the source directory to the target directory:

hdfs dfs -mkdir [***DIRECTORY-NAME***]

hdfs dfs -mv [***COMPLETE-PATH-TO-S3-BUCKET***]/[***SOURCE-DIRECTORY***] [***COMPLETE-PATH-TO-S3-BUCKET***]/[***TARGET-DIRECTORY***]

DWX-6674: Hue connection fails on cloned Impala Virtual Warehouses after upgrading: Problem: If you clone an Impala Virtual Warehouse from a recently upgraded Impala Virtual Warehouse, and then try to connect to Hue, the connection fails.; Workaround: Create a new Impala Virtual Warehouse and do not clone from a recently upgraded warehouse. Then the connection to Hue from the new Impala Virtual Warehouse succeeds.
DWX-5650: Hue only makes the first user a superuser for all Virtual Warehouses within a Data Catalog: Problem: Hue marks the user that logs in to Hue from a Virtual Warehouse for the first time as the Hue superuser. But if multiple Virtual Warehouses are connected to a single Data Catalog, then the first user that logs in to any one of the Virtual Warehouses within that Data Catalog is the Hue superuser.
For example, consider that a Data Catalog DC-1 has two Virtual Warehouses VW-1 and VW-2. If a user named John logs in to Hue from VW-1 first, then he becomes the Hue superuser for all the Virtual Warehouses within DC-1. At this time, if Amy logs in to Hue from VW-2, Hue does not make her a superuser within VW-2.; None.
