Hi Swetha,
Would you mind elaborating your usage scenario of DStream unpersisting?
>From my understanding:
1. Spark Streaming will automatically unpersist outdated data (you already
mentioned about the configurations).
2. If streaming job is started, I think you may lose the control of the
job, when do you call this unpersist, how to call this unpersist (from
another thread)?
Thanks
