Subject Only one Active task in Spark Structured Streaming application
Date Thu, 21 Jan 2021 11:12:19 GMT

My Spark Structured Streaming application was performing well for quite
some time but all of a sudden from today it has slowed down. I noticed in
the Spark UI that the 'No. of Active Tasks' is 1 even though 64 Cores are
available. (Please see the attached image).

I don't believe there's any data skew issue related to partitioning of
data. What could be the reason for this? Please advise. Thanks.
