> The CombineFileInputFormat is too aggressive at combining file blocks unless a sensible
mapred.max.split.size value is set in the Configuration or is explicitly configured on the
CombineFileInputFormat class itself. This JIRA seeks to set intelligent defaults for the max
split size in the case that a default is not already provided and provide a way for Crunch
clients to override the defaults via a configuration parameter.
