title: ERROR ql.Driver (SessionState.java:printError(419)) - FAILED: Execution Error, return code -101 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
body: <p>As I have 5 node cluster with 1 Hadoop node in DSE. I 'm trying to execute Analytics with HiveQL on <code>Hiveserver2</code> thru <code>JDBC</code> connection remotely. After every <code>50 /54 jobs</code> I'm getting error in Hive log:</p>
  
  <pre><code>ERROR ql.Driver (SessionState.java:printError(419)) - FAILED: Execution Error,
   return code -101 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask
  </code></pre>
  
  <p>And after that <code>hiveserver2</code> stop making connection. I'm not sure may be <code>"hive.server2.async.exec.threads = 50"</code> is the root cause.</p>
  
  <p>Can you please suggest any solution on this error?</p>
