Checksum error during checkpointing

["Lalwani, Jayesh" <Ja...@capitalone.com>]

We have a Structured Streaming application running for more than 40 hours. We are storing checkpoints in EFS. The application is failing with a checksum error on the checkpoint (stack trace below)

Is this because the checkpoint is corrupt? Is there a way to fix this? Is this a bug in Spark?
