Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Affects Versions: 1.1.0
Reporter: Stefán Baxter

Priority: Minor
avg(<some-interval-value>) returns:
Error: SYSTEM ERROR: SchemaChangeException: Failure while materializing
expression.
Error in expression at index 0. Error: Missing function implementation:
[$sum0(INTERVALDAY-OPTIONAL)]. Full expression: null.

in my case this is the result of avg(<timestamp>-<timestamp>).
