Check DFS_CLIENT_READ_SHORTCIRCUIT when initializing userWithLocalPathAccess.
What should happen if DFS_CLIENT_READ_SHORTCIRCUIT is false but
DFS_BLOCK_LOCAL_PATH_ACCESS_USER_KEY is set to some user?
{quote}
Datanode will allow getBlockLocalPathInfo if the user has local path access.
DFS_CLIENT_READ_SHORTCIRCUIT is a client side configuration and should be
configured in the application using the HDFS client.
