Description

Impala uses FileSystem#getBlockLocation to get block locations. We can add isStriped() method for it to easier determine the block is belonged to replicated file or striped file.

In HDFS, this isStriped information is already in HdfsBlockLocation#LocatedBlock#isStriped(), adding this method to BlockLocation does not introduce space overhead.
