title: TableNotFoundException when upgrading hbase client from 0.98 to 1.1
body: <p>I've just upgraded to HortonWorks HBase client 1.1.2.2.4.2.0-258 from version 0.98. All works fine locally, but under production load after a couple of minutes I'm starting to have TableNotFoundException:</p>

  <p>The behaviour seems random and unpredictable, e.g. repeating the same request just works (i.e. no exception is thrown and data are successfully retrieved)</p>
  
  <p>I was trying to understand what was changed from 0.98 to 1.1 and the only significant thing I found was <a href="https://issues.apache.org/jira/browse/HBASE-16973" rel="nofollow noreferrer">https://issues.apache.org/jira/browse/HBASE-16973</a></p>
  
  <p>Playing around with those values didn't help. </p>
  
  <p>Any thing else I should take into account? Any pointers are highly appreciated!</p>
  
  <p>Thanks!</p>
