Hong Tang commented on HADOOP-6532:
-----------------------------------

Is it possible to keep the Path object, but avoid materializing the fields?

> 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.
