Set up directory permissions

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

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

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

Configure

The following changes need to be applied to the 

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

Configure WebHDFS port

1. D s config

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

   Code Block
   "webhdfs.port": <webhdfs_port_num>,

   
   

3. Save your changes.

Configure Resource Manager port

Hortonworks uses a custom port number for Resource Manager. You must update the setting for the port number used by Resource Manager.

"yarn.resourcemanager.port": 8032,

Save your changes.

Configure location of Hadoop bundle JAR

1. Set the value for the Hadoop bundle JAR to the appropriate distribution. The following is for Hortonworks 2.6:

   Code Block
   "hadoopBundleJar": "hadoop-deps/hdp-2.6/build/libs/hdp-2.6-bundle.jar"

   
   

2. NOTE: If you are using HDP 2.6.5.307-2 and above, there is a known incompatibility between the cluster and the version of the Hadoop bundle JAR that is shipped with the product. The workaround solution is to use bundle JARs from an earlier compatible version. Please set the following properties in the Admin Settings page:
   

   Code Block
   "hadoopBundleJar": "hadoop-deps/hdp-2.6.5/build/libs/hdp-2.6.5-bundle.jar"

   
   

   Code Block
   "data-service.hiveJdbcJar": "hadoop-deps/hdp-2.6.5/build/libs/hdp-2.6.5-hive-jdbc.jar"

   
   

   Code Block
   "spark-job-service.hiveDependenciesLocation": "%(topOfTree)s/hadoop-deps/hdp-2.6.5/build/libs",

   
   

3. Save your changes.

Configure Hive Locations

If you are enabling an integration with Hive on the Hadoop cluster, there are some distribution-specific parameters that must be set. For more information, see Configure for Hive.
