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

The Firebug warning is not relative to this patch. It is triggered by "org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.BlockPoolSlice.validateIntegrityAndSetLength(File,
long) " which has an update for HADOOP-10930. I will notify the owner of HADOOP-10930 for
this issue.

> 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.
