Tsz Wo (Nicholas), SZE updated HADOOP-6532:
-------------------------------------------
Description:
Compared with java.lang.String, org.apache.hadoop.fs.Path is much heavier since
it contains URI. The size of a Path is roughly 3 times of a String. See some
numbers in the comments.
A major impact of decreasing Path size is allowing ls, archive, etc. on
directories with many files.
