Hi Ken, Yes - we are on 1.4. Thanks for that link - it certainly now explains how things are working :)
We currently don’t have HADOOP_CLASSPATH env var setup and “hadoop class path” command basically points to HDP2.6 locations (HDP = Hortonworks Data Platform). Best guess I have for this right now is HDP2.6 back ported some 2.9 changes into their distro. This is on my list to get to the bottom of (hopefully no hiccups till prod) - we double checked our Salt Orchestration packages which were used to built the cluster but couldn’t find a reference to hadoop 2.9. For now, we are moving on with our testing to prepare for deployment with hadoop free version which is using hadoop classpath as described in FLINK-7477.
