Subject [jira] [Commented] (HDFS-7827) Erasure Coding: support striped blocks in non-protobuf fsimage
Date Wed, 11 Mar 2015 09:15:39 GMT

Hui Zheng commented on HDFS-7827:
---------------------------------

Hi Jing
I agree that we need a flag to identify the striped block, but could we use the STORAGE_POLICY_ID
in header of INodeFile?

> HDFS-7749 only adds code to persist striped blocks to protobuf-based fsimage. We should
also add this support to the non-protobuf fsimage since it is still used for use cases like
offline image processing.
