Haohui Mai commented on HDFS-6673:
----------------------------------
bq. user can leverage laptop's SSD to get decent performance ...
That's a bold assumption. Even SSD can deliver 50x more IOPS, it still requires
20 hours to process the fsimage.
bq. In summary, we suggest to use the PB OIV tool as following:
As pointed out the tool does not handle all existing use cases today. It is
insufficient to just support in the implementation. It is important to document
the use cases and make it explicit on to which extent the tool is applicable.
Please file a follow up jira to fix the documentation issue.
