Subject Debugging tools for Spark Structured Streaming
Date Fri, 30 Oct 2020 00:02:11 GMT
We're using Spark 2.4. We recently pushed to production a product that's
using Spark Structured Streaming. It's working well most of the time but
occasionally, when the load is high, we've noticed that there are only 10+
'Active Tasks' even though we've provided 128 cores. Would like to debug
this further. Why are all the Cores not getting used? How do we debug this?
Please help. Thanks.
