Subject ArrayIndexOutOfBoundsException in PQS
Date Thu, 05 Jan 2017 06:12:23 GMT
We noticed that PQS started raising ArrayIndexOutOfBoundsException in our
production cluster. This exception is raised sporadically and goes away
when PQS is restarted. Does anyone know what might be causing this
exception? Are there any configuration (PQS and/or Avatica) parameters that
we can modify to prevent it from recurring?

CDH 5.7.2
HBase: 1.2.0
Phoenix: 4.7

Here is an error stack for "closeStatement" request:
