Subject [jira] [Commented] (HDFS-11150) [SPS]: Provide persistence when satisfying storage policy.
Date Wed, 11 Jan 2017 01:54:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15816821#comment-15816821
] 

Yuanbo Liu commented on HDFS-11150:
-----------------------------------

[~umamaheswararao] Thanks for your response.
{code}
When we finish the movement successfully, we should clean Xattrs.
When we disable SPS dynamically, we should clean Xattrs
{code}
I was considering raising a JIRA to fix it because it's part of retry mechanism and it's not
very easy to remove xattar in {{BlockStorageMovementAttemptedItems}} right now.

The others look good to me, I'll address them today. Thanks again for your comments.

> Provide persistence for SPS in case that Hadoop cluster crashes by accident. Basically
we need to change EditLog and FsImage here.
