Fabian Hueske commented on FLINK-12008:
---------------------------------------
Yes, IIRC we recently added support for multiple paths to Flink's
{{FileInputFormat}} as well.
> Support read a whole directory or multiple input data files for read apis of
> HadoopInputs

> Key: FLINK-12008
> URL: https://issues.apache.org/jira/browse/FLINK-12008
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / Hadoop Compatibility
> Reporter: vinoyang
> Assignee: vinoyang
> Priority: Major
>
> Currently, the read APIs provided by {{HadoopInputs}} only can read one path.
> I think it's not strong enough. We should support read a whole directory or
> multiple input files.
> Hadoop provides {{org.apache.hadoop.mapred.FileInputFormat.setInputPaths()}}
> to support this requirement.
> Spark's {{sequenceFile}} API calls this
> API([https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L1049].)
> Flink calls {{org.apache.hadoop.mapred.FileInputFormat.addInputPath}} which
> only supports one path.
