Subject Re: connect refused in sqoop2 commandline
Date Wed, 17 Jul 2013 14:50:18 GMT

would you mind taking a look into sqoop.log file? It should be stored inside log directory
that was configured in sqoop.properties file [1].

Shared catalina log unfortunately do not contain any interesting information.
