Cheng Lian created SPARK-14273:
----------------------------------
Summary: Add FileFormat.isSplittable to indicate whether a format
is splittable
Key: SPARK-14273
URL: https://issues.apache.org/jira/browse/SPARK-14273
Project: Spark
Issue Type: Sub-task
Affects Versions: 2.0.0
Reporter: Cheng Lian
{{FileSourceStrategy}} assumes that all data source formats are splittable and
always splits data files by fixed partition size. However, not all HDSF based
formats are splittable. We need a flag to indicate that and ensure that
non-splittable files won't be split into multiple Spark partitions.
(PS: Is it "splitable" or "splittable"? Probably the latter one? Hadoop uses
the former one though...)
