Dave Beech created CRUNCH-146:
---------------------------------
Summary: Jobs given Avro input data without '.avro' extension
succeed, but do nothing
Key: CRUNCH-146
URL: https://issues.apache.org/jira/browse/CRUNCH-146
Project: Crunch
Issue Type: Bug
Components: Core
Affects Versions: 0.4.0
Reporter: Dave Beech
Assignee: Josh Wills
The Crunch AvroInputFormat class explicitly checks each input path for a
'.avro' extension.
If none of the input paths have such an extension, the job continues and
succeeds even though no map tasks get allocated, and none of the pipeline
stages are executed.
( I notice this behaviour is taken from Avro's own input format. It does happen
in standard Avro mapreduce too therefore, but only in the old mapred API - the
new mapreduce API version will happily read files regardless of extension. I'm
going to report this as a bug on Avro as well...)
