title: Mongodb BI Connector & Tableau: Error while trying to run mongosqld
body: <p>I'm trying to connect Tableau to MongoDB using MongoDB BI Connector and this instruction (version 2.1 (current)):</p>
  
  <p><a href="https://docs.mongodb.com/bi-connector/v2.1/installation/" rel="nofollow noreferrer">https://docs.mongodb.com/bi-connector/v2.1/installation/</a></p>
  
  <p>but I get an error in step 5:</p>
  
  <pre><code>mongosqld --schema=schema.drdl --mongo-uri=mongodb://localhost:27017

  </code></pre>
  
  <p><code>mongosqld</code> is installed properly:</p>
  
  <pre><code>mongosqld --version
  
  mongosqld version v2.1.0
  git version: 518180ba2c547d2cc6071f955d98ec6de730c0c9
  </code></pre>
  
  <p>also, my <code>mongod</code> is running and working with the default port (27017) by running this command:</p>
  
  <pre><code>sudo mongod --dbpath /mnt/PROJET-CIRMAR-1T/
  </code></pre>
  
  <p>Do you have any idea that what's the problem with running <code>mongosqld</code>?</p>
