Thank you Nitin. We saw this particular issue was due to incorrect host address being set. We got it to work today by setting the DRILL_HOST_NAME environment variable to the pod's IP address. We are running into a separate issue with memory allocation when querying large files (> 400mb) from s3. But, that might be more related to fine tuning the configuration. We will try out your suggestion.
