very long time and timesout
Spark101 created SPARK-36912:
--------------------------------
Summary: Get Result time for task is taking very long time and timesout
Key: SPARK-36912
URL: https://issues.apache.org/jira/browse/SPARK-36912
Project: Spark
Issue Type: Question
Components: Block Manager
Affects Versions: 3.0.3
Reporter: Spark101
Attachments: Stage-result.pdf, Storage-result.pdf, environment.pdf, executors.pdf, thread-dump-exec3.pdf, threadDump-exc2.pdf
We use Spark on Kubernetes to run batch jobs to analyze flows and produce insights. The flows are read from timeseries database. We have 3 exec instances each having 5g mem + driver (5g mem). We observe the following warning followed by timeout errors after which the job fails. We have been stuck on this for some time and really hoping to get some help from this forum:2021-10-02T16:07:09.459ZGMT WARN dispatcher-CoarseGrainedScheduler TaskSetManager - Stage 52 contains a task of very large size (2842 KiB). The maximum recommended task size is 1000 KiB.
