Hi Murthy, The error fails because the argument is set, but the query doesn't expect any. Actually, the Query class was created only for testing purposes and apparently was broken at some point. This project is created to run all the queries from Zeppelin to demonstrate its integration with Ignite.
'null' is the valid name for a cache. In case of SQL it's treated as the default schema and is used in the demo for simplicity. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Help-with-Ignite-Zeppelin-Demo-tp3681p3684.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
