MultipleTsvFiles

case class MultipleTsvFiles(p: Seq[String], fields: Fields = cascading.tuple.Fields.ALL, skipHeader: Boolean = false, writeHeader: Boolean = false) extends FixedPathSource with DelimitedScheme with Product with Serializable

Allows the use of multiple Tsv input paths. The Tsv files will be process through your flow as if they are a single pipe. Tsv files must have the same schema. For more details on how multiple files are handled check the cascading docs.

    Determines if a path is 'valid' for this source.

    Determines if a path is 'valid' for this source. In strict mode all paths must be valid. In non-strict mode, all invalid paths will be filtered out.

    Subclasses can override this to validate paths.

    The default implementation is a quick sanity check to look for missing or empty directories. It is necessary but not sufficient -- there are cases where this will return true but there is in fact missing data.

    TODO: consider writing a more in-depth version of this method in TimePathedSource that looks for TODO: missing days / hours etc.

If you set this to true, the mock in TestMode will be considered to be a mock of the Tap (which must be transformed) and not the Source.
