Hadoop client JDK interoperability to communicate with Cloudera cluster

At the moment we have both our Hadoop cluster (CDH 4.1.2) and services that communicate with it via a hasoop client running in Java 6. We plan to move these client components to Java 8, leaving the Hadoop servers. running on top of Java 6 since they are now because Cloudera only announced support for JDK 8 since version 5.3.0 and we have no plans to update Hadoop - details here: https://www.cloudera.com/content/cloudera/ en / documentation / core / latest / topics / cdh_rn_new_in_530.html
So our problem is whether different Java versions in the cluster (6) and in the client components (8) cause any problems. The internet hasn't been of much help while Hadoop Java compatibility is mostly discussed regarding server component migration, so please share your experience pertaining to this if you have one.
