I encountered similar issue with HDFS_CLIENT, I've successfully deleted the client using curl call as mentioned in your post.
But, Installation of HDFS_CLIENT stuck at:
2017-01-24 08:44:43,873 - Package['unzip'] {}
And installation failed with following error message:
stderr: /var/lib/ambari-agent/data/errors-2631.txt
Python script has been killed due to timeout after waiting 1800 secs
