Zhe Zhang commented on HDFS-7616:
---------------------------------
Thanks for working on this [~tfukudom].
The unit test in your patch passes because it only verifies the existence of
the file. Although configured with EC policy, the file's inode is still an
INode instance and will be saved in FSImage without any additional logic. This
JIRA should make sure the information of striped blocks in the file is
corrected saved in FSImage. I think HDFS-7827 shares a similar purpose and
handles legacy FSImage. This JIRA should handle the new FSImage format.
