Subject [jira] [Commented] (CRUNCH-331) Change default settings for CombineFileInputFormat
Date Mon, 03 Feb 2014 18:34:08 GMT

Josh Wills commented on CRUNCH-331:
-----------------------------------

Even more minimal solution: just set the crunch.disable.combine.file flag to true in the From.formattedFile
function and At.formattedFile functions.

> Currently, we default to enabling the CombineFileInputFormat settings for any extensions
of FileSourceImpl b/c it tends to improve performance for common file formats like text, sequence
files, and Avro files. However, this default has caused problems for formats like Parquet
and for custom file formats that have complex split logic.
> This JIRA is to track modifying the default combine file settings in at least some contexts,
such as with From.formattedFile for custom input formats.
