title: Impala Query Editor always shows AnalysisException
body: <p>I am running a Quickstart VM Cloudera on a Windows 7 computer, with 8Go of RAM and 4Go dedicated to the VM.</p>
  
  <p>I loaded tables from a SQL database into Hive, using Sqoop (Cloudera VM tutorial exercise 1). Using the Hive Query Editor OR Impala Shell, everything works fine (i.e. "show tables" shows me the tables that were imported).</p>
  
  <p>Using the Impala Query Editor, whatever I type, I get the same error message:</p>
  
  <pre><code>AnalysisException: Syntax error in line 1: USE `` ^ Encountered: EMPTY IDENTIFIER Expected: IDENTIFIER CAUSED BY...
  </code></pre>

  <p>I have the same if I type "show tables;" ...</p>
  
  <p>I checked that Impala-services were up and running and it was the case, and everything works fine in the Impala shell:</p>
