Hi All, I was trying to write an implementation of storage interface for elastic search, so that notebooks can be highly available in a cluster. The implementation of basic interface looked simple but I got stuck while importing note.json data into elastic search. Unfortunately, the type of paragraphs.result varies. In my sample notebook, for one paragraph, it was an object containing fields "code", "type" and "msg", while in another paragraph, it was a string "org.apache.zeppelin.interpreter.InterpreterException: org.apache.thrift.transport.TTransportException: java.net.ConnectException: Connection refused". This is not acceptable in elastic search, since the type of a field should be same for an index. There might be some complex alternative, where once can split notebook into multiple indices, based on the type of paragraphs.result, but that is more of a hack.
Can someone please suggest a simple and clean alternative for this. I am also curious about the reason for keeping different types for the same variable in Zeppelin. Regards, Ashish
