Subject [jira] [Commented] (HADOOP-15837) DynamoDB table Update can fail S3A FS init
Date Tue, 09 Oct 2018 22:13:03 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15837?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16644159#comment-16644159

Steve Loughran commented on HADOOP-15837:

Patch 001. 
# change case statement so that updating == active as far as init is concerned, consistent
with the AWS docs
# error handing/retries around waitForTable access, with tests

I'd actually implemented change #2 and was testing it before I found the AWS docs which said
yes, updating is good to go —the most minimal patch is just that switch statement change.
I'm putting this patch here fore review and will then roll it back. Table creation is rare
enough in production that retries there aren't a real need; the use case "on-demand-create"
is more a test/explorative option.

Tested. Yes, but only as part of HADOOP-14556, and not (yet) successfully recreated the updating
failure (or it did happen but now it didn't fail)

> When DDB autoscales a table, it goes into an UPDATING state. The waitForTableActive operation
in the AWS SDK doesn't seem to wait long enough for this to recover. We need to catch &
