This is what we obeserved: 1. Sometimes when increasing the replication factor of a file, some blocks belonged to this file do not get to increase to the new replication factor. 2. When taking meta save in two different days, some blocks remain in under-replication queue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
