Hi, I was trying to query on process and task instance data using spark-sql which published from BPMNDataPublisher to the DAS. Here I need to convert the date string (eg: Thu Sep 24 09:35:56 IST 2015) into one of the datetime format that allows in spark. I think it is not possible to query date directly from spark-sql so I'm thinking of writing a user define function for it.
Is it possible to write udf in spark-SQL (like in hive) and if possible how can I import it into das to run the script? (Please find the attached image of the sample data which stored in the das side) -- Isuru Wijesinghe *Software Engineer* Mobile: 0710933706 isur...@wso2.com
