Can there be any incompatibility issues with Edge node having lower HDP and OS version than the cluster?

New Contributor

I have an edge node (VM, not managed by Ambari) HDP 2.3.2 on RHEL 6 while the cluster has HDP 2.4.2 RHEL 7. Will there be any version incompatibility issues with this configuration?

Hi @Shishir Jaiswal,

Assuming HDP components on the Edge nodes such as clients and Knox then mixed versions are not supported. Knox for example only supports specific versions of an Hadoop service (see section 2.8.1.2 in http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.0/bk_security/bk_security-20160829.pdf). Mixed OS versions do most times not affect things as long as it's fullfil all requirements around libraries, JVM versions etc.

/Best regards, Mats
