title: Querying MapR with db-shell - where clause
body: <p>The following works: </p>
  
  <pre><code>mapr dbshell 'find /sourcepath --q {"$select":"source","$where":{"$and":[{"$eq":{"status":"file_LOAD_START"}}]}}'
  </code></pre>
  
  <p>The following works too: </p>
  
  <pre><code>mapr dbshell 'find /sourcepath --q {"$select":"source","$where":{"$and":[{"$eq":{"car_id":"number"}}]}}'
  </code></pre>
  
  <p>But the following does not work</p>
  
  <pre><code>mapr dbshell 'find /sourcepath --q {"$select":"source","$where":{"$and":[{"$eq":{"status":"file_LOAD_START"}}, {"$eq":{"car_id":"number"}}]}}'
  </code></pre>
  
  <p>The error message states</p>
  
  <p>"You cannot specify '{"$eq":{"car_id":"number"}}]}}' as another value for the default ('') option in a single command.
  You already provided '/sourcepath' earlier.
  Did you forget to add quotes around the value of another option?"</p>
