Subject [jira] [Created] (DRILL-5512) Standardize error handling in ScanBatch
Date Mon, 15 May 2017 21:35:04 GMT
Paul Rogers created DRILL-5512:

             Summary: Standardize error handling in ScanBatch
                 Key: DRILL-5512
                 URL: https://issues.apache.org/jira/browse/DRILL-5512
             Project: Apache Drill
          Issue Type: Improvement
    Affects Versions: 1.10.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers
            Priority: Minor
             Fix For: 1.10.0

ScanBatch is the Drill operator executor that handles most readers. Like most Drill operators,
it uses an ad-hoc set of error detection and reporting methods that evolved over Drill development.

This ticket asks to standardize on error handling as outlined in DRILL-5083. This basically
means reporting all errors as a {{UserException}} rather than using the {{IterOutcome.STOP}}
return status or using the {{FragmentContext.fail()}} method.

This work requires the new error codes introduced in DRILL-5511, and is a step toward making
readers aware of vector size limits.
