title: Apache Hive not able to delete rows from table
body: <p>I am using Apache Hive latest available version viz. apache-hive-1.2.1.
  It is said that Apache Hive now supports Update, Delete statements. </p>
  
  <p>But I am not able to delete rows. Behavior is as follows. </p>
  
  <pre><code>hive&gt; delete employee;
  Usage: delete [FILE|JAR|ARCHIVE] &lt;value&gt; [&lt;value&gt;]*
  Query returned non-zero code: 1, cause: null
  
  hive&gt; delete * from employee;
  Usage: delete [FILE|JAR|ARCHIVE] &lt;value&gt; [&lt;value&gt;]*
  Query returned non-zero code: 1, cause: null
  
  hive&gt; delete from employee where 1=2;
  FAILED: SemanticException [Error 10294]: Attempt to do update or delete     using transaction manager that does not support these operations.
  </code></pre>
  
  <p>EDIT : Discussion at <a href="https://stackoverflow.com/questions/17810537/how-to-delete-and-update-a-record-in-hive">How to delete and update a record in Hive</a>  mentions that new version of Hive supports these operations. But my experience here is different. 
  So this question is specific to new version and how to enable these operations. </p>
