    Running Report Designer 5.1 on Ubuntu 14.04, with the Hadoop version in /Pentaho/design-tools/report-designer/plugin.properties set to cdh50, I can set up a connection to an Impala database on another server, and the test returns an OK status. Setting up a data source, selecting the Impala connection, and editing the query, when I select the 'default' DB in the query editor I get the following error (note, it's inconvenient having to close every wizard window before I can view it!): java.lang.ClassCastException: org.pentaho.hadoop.shim.common.DriverProxyInvocationChain$ConnectionInvocationHandler cannot be cast to java.sql.Connection at
