Excerpt

Set up directory permissions

On all Hortonworks cluster nodes, verify that the YARN user has access to the YARN working directories: 

Code Block
chown yarn:hadoop /mnt/hadoop/yarn

If you are upgrading from a previous version of Hortonworks, you may need to clear the YARN user cache for the

D s defaultuser
Typehadoop
Fulltrue
user:

Code Block
rm -rf /mnt/hadoop/yarn/local/usercache/trifacta

Configure 
D s platform

The following changes need to be applied to the 

d-s-item
item
node
.

Except as noted, these changes are applied to the following file in the 

D s item
itemdeployment
:

D s triconf

Configure WebHDFS port

  2.  WebHDFS: Verify that the port number for WebHDFS is correct:
