> I find in JdbcHiveMRInput.java , the  system save flat table with TextFile.
> However in SparkCubingByLayer.java, the system getFlatTableStorageFormat is SequenceFile
.It read the flat table as SequenceFile and failed.
> I workaround with add property "kylin.source.hive.flat-table-storage-format=TEXTFILE"
in cube.
> But I think maybe we could do it better.
