[jira] [Commented] (HADOOP-13966) add ability to start DDB local server in every test

    [ https://issues.apache.org/jira/browse/HADOOP-13966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15927097#comment-15927097 ] 

Mingliang Liu commented on HADOOP-13966:
----------------------------------------

So right now we use DDBLocal only in uni tests - the only one by now is TestDynamoDBMetadataStore. For integration tests, we always use the real DDB web service. Are you suggesting we make it possible to run the integration tests against DDBLocal? I'm +1 on the idea for faster/cheaper debugging. Nice to have. We may need a specialized DDBClientFactory class for connecting a standalone DDBLocal server for that.

> the local in memory DDB starts up in only 2+ seconds, so we have to reason to not use it in all our integration tests, if we add a switch to do this
