Hm, sorry to say that you might have better luck at getting to the bottom
of this at Hortonworks’ user forums since people there are more likely to
have played with Apex and the like. The stack trace you included is
actually a pretty generic one so it’d be hard for someone to see those
lines and chime in with a specific cause without way more details about
your use case and the configuration of your cluster. If I had to guess,
there’s probably some tuning that might be needed within your HBase/Apex
configuration, but you’re venturing into things that people familiar with
HDP are more likely to be able to help out with.
