Create a Proxy Directory for MapR

Create a Proxy Directory for MapR

If the Hadoop cluster runs on MapR, you must create a proxy directory for the user who will impersonate other users.
Verify the following requirements for the proxy user:
  • Create a user or verify that a user exists on every Data Integration Service machine and on every node in the Hadoop cluster.
  • Verify that the uid and the gid of the user matches in both environments.
  • Verify that a directory exists for the user on the cluster. For example,
    /opt/mapr/conf/proxy/<user name>


We’d like to hear from you!
