Description

Split strategy chosen by OrcInputFormat should not change when enabling or disabling footer cache. Currently if footer cache is disabled minSplits in OrcInputFormat.Context will be set to -1 which is used during determination of split strategies. minSplits should be set to requested value or some default instead of cache size
