We might have a stale hbase-site.xml deployed along the code which runs on
Spark.
however what we set is the Zookeeper quorum for the right cluster.
I was told that the third Batch starts to throw errors like these and the first
two are fine. But then again I'm not running this myself
We're going to increase the log level to DEBUG to see if we see anything.

Subject: Re: How to get useful info from Client exceptions
The exception is composed this way (see AsyncProcess):
return new RetriesExhaustedWithDetailsException(new
ArrayList<Throwable>(throwables),
new ArrayList<Row>(actions), new ArrayList<String>(addresses));
In your case there were 10456 UnknownHostException's.
Was there any other clue in client side log ?
I think one improvement we can do is selectively logging which host(s) was
involved in the UnknownHostException's.
BTW was hbase-site.xml on the classpath of your client ?
