Configure Separate Hive Data and Metadata Directories for Hue

About this task

If you want to store Hue data and metadata in separate directories from Hive data and metadata, follow these steps:

Procedure

Copy hive-site.xml to a new location. (The original hive-site.xml file remains in the previous location for use by Hive.)
Edit hue.ini and change the hive_conf_dir property so it points to the new location for hive-site.xml.
Change the hive.metastore.warehouse.dir property in the new hive-site.xml file so it points to the directory where Hue data will be located.
Change the hive.metastore.uris property so it points to the directory for Hue's metastore_db.

Set the hive.metastore.execute.setugi property to true.

<property>
  <name>hive.metastore.execute.setugi</name>
  <value>true</value>
  <description> Set this property to enable Hive Metastore service impersonation in non-secure mode.
   In non-secure mode, setting this property to true causes the metastore to execute DFS operations
   using the client's reported user and group permissions. Note that this property must be set on
   BOTH the client and server sides. </description>
</property>
