Document dropping support for certain CDH and HDP versions in an upcoming release

, if you look at the comments in you will notice that all versions of HDP prior to 2.5 are vulnerable to a remotely executable namenode vulnerability, which allows an attacker to run arbitrary code as the namenode (hdfs) user, bypassing all HDFS-based security. Also, since the hdfs user is normally in the hadoop group, it gets special access to certain other on-disk locations on the individual node filesystems that should normally be protected.
