No suitable driver found for Webspoon

When run a webspoon job, get an error “No suitable driver found for jdbc:hive2://…”. But with same configuration, run fine with pdi(kettle). Check the tomcat logs, it shoule be some ports are occupied . Will post the answer once I fix this problem.

Here are the whole configuration steps for webspoon.

1. Check the hadoop version which is CDH 5.8.2
2. Enter the container , modify “active.hadoop.configuration” values to cdh510 in file /usr/local/tomcat/plugins/pentaho-big-data-plugin/plugin.properties
3. Remove the karaf cache and restart the container
4. Open webspoon and test connection which works fine.
5. And run the webspoon job, but get this error .

For the record, this issue happened for Connection Type of “Impala”, but already resolved.

At least, I can see a SSL warning, which could be resolved by setting useSSL=false as described here. Unfortunately, this is all I can tell from the log.

If it happens on Spoon, this is a bug of Spoon. Therefore, the best place to ask a Spoon question would be Pentaho Community Forums or Vantara Community. Or if you want to file a bug, please go to JIRA.
