title: Hive query vertex failure in tez mode of execution
body: <p>I'm trying to execute a Hive query -- </p>
  
  <pre><code>  Select a,b,c,d,e,f,cast(g as timestamp) - cast(f as timestamp) as runtime 
  from table ORDER BY d,e desc limit 100
  </code></pre>
  
  <p>It is falling with below error </p>
  
  <p><strong>TaskAttempt 1 failed, info=[Error: Failure while running task:java.lang.RuntimeException: java.lang.RuntimeException: java.lang. RuntimeException: Cannot find ExprNodeEvaluator for the exprNodeDesc null</strong></p>
  
  <p>I suspect this is because of the difference calculation b/w g and f (may be some NULL values ) but requesting  expert answers to solve the issue, As I don't have the access to data . thanks in advance</p>
  
  <p>I'm using below properties . </p>
  
  <pre><code>set hive.execution.engine=tez;
  set hive.exec.parallel=true; 
  set hive.auto.convert.join=false; 
  set hive.compute.query.using.state=true; 
  set hive.stats. fetch.column. stats=true;
  set hive.stats. fetch.partition.stats=true;
  set mapreduce.map.memory.mb=9000;
  set mapreduce.map.java.opts=--Xmx7200m;
  set mapreduce.reduce.memory.mb=9000; 
  set mapreduce. reduce . java. opts=-Xmx7200m;
  set hive.cho.enable=true;
  set hive. vectorized.execution.enabled=true; 
  set hive.vectorized.execution.reduce.enabled=true;
  </code></pre>
  
  <p>I'm running from the hive prompt on UNIX server . actually the underlying table is a view contains some joins .. on further research I found that we need to replace the order by . Unfortunately distribute by needs sorting before the limit -->this is also leading the same issue . Can some one please suggest any other way to rewrite the query</p>
