I need to run a Hive QL which takes date as condition. I want to pass this date by caling the NiFi job through cron/shell. Could you let me know how can I achive this in NiFi please.
Any sample flow would really helps.
@kumar79 I am not very sure with your complete use case, if you explain more would be better.
Why you want to take date from shell/cron? you can use UpdateAttribute processor with custom property and use NiFi Regular Expression language to set date for you. E.g https://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html#dates
The attribute later you can use in your flow to satisfy QL condition.
Hope it helps.
Sorry for the delay and thanks for the response. I want to avoid updating the flow incase if we have to run the flow for any old dates.
If any such request comes I just want to run the flow through shell by just passing old date.
Hope the requirement is clear to you.
