Description

Knox documentation should state the requirement to add proxy grant for knox webhcat-site.xml when knox integrates with secure hadoop webhcat.

The following documentation had to be added.

1. 1. 1. 1. Grant proxy privilege for Knox in `webhcat-stie.xml` on Hadoop master nodes ####

Update `webhcat-site.xml` and add the following lines towards the end of the file.

Replace FQDN_OF_KNOX_HOST with right value in your cluster.
You could use * for local developer testing if Knox host does not have static IP.
