I testing Spark Streaming working withSASL_SSL enabled kafka broker in a notebook.

as per this guide https://docs.databricks.com/spark/latest/structured-streaming/kafka.html

i have copied jsk files in an s3 bucket and mounted it in dbfs.

In notebook when i run dbutils.fs.head( jksPath), i can see file contents.

But when i run the spark streaming job throwing.

Thanks..Yes '/dbfs/mnt/xxxx/kafka.client.truststore.imported.jks'  path worked.

Also other workaround we got it working, is copy the file from s3 to filesystem using init script and use filepath.
