Description

DataImportHandler fails on a FileNotFoundException when FileDataSource tries to read from a named pipe. This is because FileDataSource:105 in getFile calls isFile(). Since named pipes aren't true files this fails. When this check is removed, the import is able to proceed normally.

I want to use a named pipe so I can keep the file compressed on disk and use gunzip -c to uncompress the file to the named pipe. Another way of fixing this would be to natively decompress inside of FileDataSource, it's not clear if this bug https://issues.apache.org/jira/browse/SOLR-1406 fixes the issue.

What would the preferred patch do? Should it read a forceFile attribute from initProps?
