title: Sqoop job to import data drom SQL server stuck at Map 0%
body: <p>I have a pseudo distributed hadoop cluster running CDH5.0.2. I'm running a sqoop import command:</p>
  
  <pre><code>sudo -u sqoop sqoop import --connect "jdbc:sqlserver://x.x.x.x:1433;databaseName=yyyyy" --username x --password y --table table_name
  </code></pre>
  
  <p>I'm just importing a very small table that has 12 rows and 2 columns for testing. The job has been running for half hour. On My resource manager, the mapper tasks' status are listed as NEW and their state are listed as SCHEDULED. I don't think it ever runs!</p>
  
  <p>When i list the job on yarn using:</p>
  
  <pre><code>yarn application -list
  </code></pre>
  
  <p>i'm getting:</p>
  
  <pre><code>14/07/01 15:55:06 INFO client.RMProxy: Connecting to ResourceManager at host/x.x.x.x:8032
