> Not sure if this is a good proposal, but I saw a few cases where some integration test methods in {{ITestDynamoDBMetadataStore}} timed out simply. Specially, the one keeps failing me today is {{testAncestorOverwriteConflict}}. I increase the timeout to 200s and it works for me happily. Am I using VPN and a slow home network, I'm afraid so.
> The time out rule, as inherited from base class {{HadoopTestBase}}, is 100s by default. Though that 100s time out default value can be overridden in base class via system property {{test.default.timeout}}, that's system wide affecting all other tests. Changing that time out value for one test is no better than overriding in this test {{ITestDynamoDBMetadataStore}} explicitly. I think doubling it to 200s would not be very crazy considering we are testing against a remote web service, create and destroy tables sometimes.
> Thoughts?
> [EDIT]: I meant 100s when I said 10s. Sorry for confusion.
