Kai Sasaki commented on HDFS-8196:
----------------------------------
I uploaded a patch which shows
- Default erasure coding policy information (cell size, num data/parity blocks)
- Total striped blocks
- Total striped blocks size
Information of each directory is shown through WebHDFS currently. So we can
modify WebHDFS to expose erasure coding policy information by directory in
HDFS-11394 separately.
