      Description

      If user tries to run the second drillbit process, the following output will be obtained:

      vitalii@vitalii-pc:/tmp/apache-drill-1.15.0$ bin/drill-embedded 
      java.lang.NullPointerException
      Apache Drill 1.15.0
      "This isn't your grandfather's SQL."
      sqlline> select * from (values(1));
      No current connection
      sqlline> !q
      

      For 1.14.0 drill version the output was correct (but too long):

      ./bin/drill-embedded

      Looks like it is fine to have a short message in console about the reason of error, similar to:

      java.sql.SQLException: Failure in starting embedded Drillbit: java.net.BindException: Address already in use
