[jira] [Commented] (CALCITE-2209) Support loading JSON model file through URL

    [ https://issues.apache.org/jira/browse/CALCITE-2209?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16497533#comment-16497533 ] 

Rong Rong commented on CALCITE-2209:
------------------------------------

Thanks for the pointer, I added a test for custom URLStreamHandlerFactory. Wasn't sure if it is the right way since official document indicates that the URL.setURLStreamHandlerFactory() method should only be called once every JVM. Please let me know if the implementation is non-intrusive.

> Currently, Calcite only support loading JSON model file through inline or local file. The Jira attemps to extend it to support loading JSON model file through URL, so users can implement their own URLStreamHandlerFactory to read the JSON model file from e.g., HDFS or etc.
