Subject [jira] [Commented] (YARN-6027) Support fromId for flows/flowrun apps
Date Wed, 28 Dec 2016 03:55:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-6027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15781976#comment-15781976

Varun Saxena commented on YARN-6027:

bq. However if same flow is ran multiple times in same day, they are also listed separately.

They should not be returned separately if flow has been run by same user. There will be multiple
runs but activity will only be one per day. The row key for flow activity table is cluster!dayTs!user!flow.
Can you check what was the ID returned from backend ? Is server and client time zone different

bq. Assume a user is running same applications with different flow names (yes, its may not
be a direct use case), then we are going to have multiple entries of flows. 
Yes. We identify flow by YARN tags given by the user. So if he gives different tags for same
flow, it will be treated differently.

bq. User wants to see flow activities ran on a specific day (same day range from 10.00am to
11.30am ) in past
Not supported and cannot be supported as well with current schema. The minimum time unit for
which records can be retrieved is a day. Let me know if there is a use case for above.

bq. User wants to search for flow activity with some given criteria. (name/duration etc)
This is what I suggested in an earlier comment. That we can probably support searching based
on flow name as well. Currently not supported but will be feasible to support, even though
not straight forward.

> In YARN-5585 , fromId is supported for retrieving entities. We need similar filter for
flows/flowRun apps and flow run and flow as well.
