I guess it is the usual things - if the non zookeeper processes take too much
memory , disk space etc it will negatively affect zookeeper and thus your whole
running cluster. You will have to make for your specific architectural setting
a risk assessment if this is acceptable.

Hi,
Is it necessary to deploy Apache Zookeeper and Spark in separate set of
hosts when using standby masters? What will be the consequences of running
Zookeeper quorum in the same physical machines that runs the Spark cluster.
