Description

Currently when a file format is unsupported, impalad will log an error:

E0611 13:42:47.428393 22076 ImpaladCatalog.java:201] Error adding catalog object: Expected compressed text file with {.lzo,.gzip,.snappy,.bz2} suffix: 000000_0.deflate
Java exception follows:

Catalogd should filter out unsupported files instead of letting every impalad log the error.
