Ayush Saxena commented on HADOOP-17087:
---------------------------------------
For just EC policy you can use getErasureCodingPolicy() or hdfs ec admin
commands
Check here :
https://hadoop.apache.org/docs/r3.2.1/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html#Administrative_commands
hdfs ec -getPolicy <path> will help.
I guess there is bunch of ways to get the desired result already and moreover
you can't change the CLI output the command for F option. Changing CLI output
is incompatible and isn't allowed, if required you need a new option for that,
for which I don't think there is very strong need, provided we need to handle
the cases for the FileSystem's which don't support EC and stuffs like that.

> We currently do not have a brief way to judge an ec file. {{hdfs fsck}} can
> do but shows too much information. Neither {{du}} nor {{ls}} can accurately
> judge the ec file.
> So I added ec flag to stat cli.
> old result:
> {code:java}
> $ hadoop fs -stat "%F" /user/ec/ec.txt
> regular file
> $ hadoop fs -stat "%F" /user/rep/rep.txt
> regular file
> {code}
> new result:
> {code:java}
> $ hadoop fs -stat "%F" /user/ec/ec.txt
> erasure coding file
> $ hadoop fs -stat "%F" /user/rep/rep.txt
> replica file
> {code}
