Hi Spark Users,
I'm seeing checkpoint restore failures causing the application startup to
fail with the below exception. When I do "ls" on the s3 path I see the key
listed sometimes and not listed sometimes. There are no part files
(checkpointed files) in the specified S3 path. This is possible because I
killed the app and restarted as a part of my testing to see if kinesis-asl
library's implementation of lossless kinesis receivers work.
Has anyone seen the below exception before? If so is there a recommended
way to handle this case?
15/10/09 21:02:09 DEBUG S3NativeFileSystem: getFileStatus could not find
key '<insert s3 key to the checkpointed rdd>'
Exception in thread "main" java.lang.IllegalArgumentException: requirement
failed: Checkpoint directory does not exist: <insert full s3 path to the
checkpointed rdd>
