Exception attempting to read userData.json

[michaeljfazio]

I'm running HBase on EMR backed by S3. When ingesting data, the following exception is always thrown at some point. It doesn't seem to cause an issue, the data still imports correctly as far as I can tell.

this issue needs to grive read-only privilege for others in all nodes

sudo chmod 444 /var/aws/emr/userData.json

default is 440
