Subject [jira] [Commented] (HADOOP-13449) S3Guard: Implement DynamoDBMetadataStore.
Date Sun, 20 Nov 2016 16:46:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15681442#comment-15681442

Steve Loughran commented on HADOOP-13449:
-----------------------------------------

correction; I can't talk monday, other commitments.

w.r.t SDK and jackson, we're going to have to upgrade jackson and the SDK on branch-2, using
a jackson version that is compatible at the API level with existing code. This is going to
cause problems downstream, but we don't really have a choice any more.

the jackson update should go in as HADOOP-12705

I'm also going to have to update the aws SDK in 2.7 and 2.8; troublesome that. We need to
get rid of org.json artifacts embedded in the existing AWS SDK, which means update SDK, which
means Jsckson update, unless I can do one of: (a) shade everything or (b) swap in tdunning's
org.json replacement (more specifically: cut the org.json lib off the AWS JAR and explicitly
add ted's replacement)
