Spark job writing to MapR DB JSON hangs (sometimes) on larger tables

So we actually opened a ticket with MapR about this and we ended up closing it because the job started working again.

We have a 22 node cluster with 36gb of memory assigned to the YARN containers - We feel like the code works because  it has completed many times -but will fail once in a while for no apparent reason  is there some configuration with MapR DB I should be checking? The dataset is about 4 million rows - We are using MapR 6.0.1
