There is a high possibility that we might be sharing connection among
multiple threads. This MR job is fairly complicated because we spin up a

Make sure you're not sharing the same Connection between multiple threads

James

Hi,
We are running HDP2.3.4(HBase 1.1 and Phoenix 4.4). I have a MapReduce job
thats writing data to a very simple Phoenix table. We intermittently get
and due to this our job fails:
java.util.ConcurrentModificationException at
java.util.HashMap$HashIterator.remove(HashMap.java:944) at
