Subject [jira] [Commented] (HDFS-7827) Erasure Coding: support striped blocks in non-protobuf fsimage
Date Mon, 09 Mar 2015 02:21:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14352435#comment-14352435
] 

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

To support striped block in no-protobuf fsimage we only need to persist striped blocks in
non-protobuf format.
The BlockInfo class  uses writable  interface to persist itself in non-protobuf format. So
we can override the write method to implement it.

> 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.
