Zhe Zhang commented on HDFS-9604:
---------------------------------
Thanks for the suggestion [~walter.k.su] (and sorry for responding late).
Actually per our discussion on HDFS-8833, when we support multiple EC policies
(being tracked under HDFS-9658), {{INodeFile#IS_STRIPED}} will be extended to
represent EC policy of the file. So I guess it's still part of file metadata.
The patch doesn't actually touch {{ErasureCodingPolicyManager}}. Is the JIRA
about {{ErasureCodingPolicy}} or {{ErasureCodingPolicyManager}}?
