Xiao Chen commented on HDFS-12819:
----------------------------------
Thanks for creating the jira and posting patches Eddy.
Can we change the text:
Warning: setting erasure coding policy on *an* non-empty directory will not
automatically convert existing *data* to...
- typo 'an' to 'a'
- change existing data to existing file
While we're at it, could you please add a line
tohttp://hadoop.apache.org/docs/r3.0.0-beta1/hadoop-project-dist/hadoop-hdfs/HDFSErasureCoding.html#Administrative_commands,
for {{-setPolicy}}, to explain the same? Maybe like below:
Note: Setting policy on a non-empty directory will not automatically convert
existing file to that policy. To change policy on existing files, please copy
that file.
+1 pending.
