---------------------------------

bq. We also need a "replicated" EC policy so we can override the EC policy on a 
parent directory and go back to just replicating the files
Hi [~andrew.wang], Instead of adding new "replicated" EC policy, how about call 
unset EC policy on  a directory and the new files under this will now start 
writing in replicated fashion. Like you mentioned in [HDFS-10996, a conversion 
tool|https://issues.apache.org/jira/browse/HDFS-10996?focusedCommentId=15613745&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15613745]
 will take care of converting all existing ec files to replicated one and vice 
versa. Its just a thought, please feel free to correct me if I missed anything. 
Thanks!

> Since the directory-level EC policy simply applies to files at create time, 
> it makes sense to make it more similar to storage policies and allow changing 
> and unsetting the policy.
