Description

In the command json file the hostname is in lower case, while in HA mode the
hdfs-site property dfs.namenode.rpc-address.

{dfs_ha_nameservices}.{nn_id} may
have upper case parts, which prevents the /common-
services/HDFS/<version>/package/scripts/params_linux.py file at line 300 from
identifying the namenode_id, as it tries to find the hostname in the proprety,
and their case doesn't match.

Either it should be fixed that the dfs.namenode.rpc-
address.{dfs_ha_nameservices}

.

{nn_id}

should be always in lower case too or
the params_linux.py should identify the namenode_id by trying to find the
hostname in the property ignoring case.
