Wei-Chiu Chuang commented on HDFS-11426:
----------------------------------------
[~andrew.wang] I caught another issue with the patch. The unset ec policy
command works for a directory, not a file.
{code}
/** Command to unset the erasure coding policy set for a file/directory */
private static class UnsetECPolicyCommand
implements AdminHelper.Command {
@Override
public String getName() {
return "-unsetPolicy";
}
@Override
public String getShortUsage() {
return "[" + getName() + " -path <path>]\n";
}
@Override
public String getLongUsage() {
TableListing listing = AdminHelper.getOptionDescriptionListing();
listing.addRow("<path>", "The path of the file/directory "
+ "from which the erasure coding policy will be unset.");
return getShortUsage() + "\n"
+ "Unset the erasure coding policy for a file/directory.\n\n"
+ listing.toString();
}
{code}

>
> The {{hdfs erasurecode}} CLI is similar to {{hdfs storagepolicies}} in terms
> of functionality, but different in terms of behavior. Let's refactor
> {{ECCli}} to be more similar to the various Admin classes we already have,
> and also make its calling syntax mimic {{hdfs storagepolicies}} as closely as
> possible.
