Subject [jira] [Updated] (HDFS-11951) Ozone: Handle potential inconsistent states while listing keys
Date Thu, 08 Jun 2017 07:54:18 GMT

     [ https://issues.apache.org/jira/browse/HDFS-11951?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Weiwei Yang updated HDFS-11951:
-------------------------------
    Description: 
In the discussions in HDFS-11779, there might be a corner case we running into the situation
that some key are deleted while we are listing them. For example

1. A list call is made say from key1 to key100 is returned.
2. Someone deletes the key100
3. A list continue call is made with startKey=key100.

We need to investigate this case and make sure this is properly handled in ozone. See more
discussion from [here | https://issues.apache.org/jira/browse/HDFS-11779?focusedCommentId=16042356&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16042356].
