> Per discussion in HADOOP-8060, a way for users to specify a checksum type on create() is needed. The way FileSystem cache works makes it impossible to use dfs.checksum.type to achieve this. Also checksum-related API is at Filesystem-level, so we prefer something at that level, not hdfs-specific one. Current proposal is to use CreatFlag.
