Andrew Wang commented on HADOOP-14957: -------------------------------------- We're supposed to deprecate in a prior major release before removing. So, we'd be violating source compatibility if we remove in 3.0. That said, it's better to do it in 3.0 than some minor release, and I think we did a similar change already for some YARN API. I think datanode reconfiguration is also only really used for DN hotswap. So, it's not *that* critical, and since we maintain wire compatibility, Hadoop 2 client JARs will keep working. > ReconfigurationTaskStatus is exposing guava Optional in its public api > ---------------------------------------------------------------------- > > Key: HADOOP-14957 > URL: https://issues.apache.org/jira/browse/HADOOP-14957 > Project: Hadoop Common > Issue Type: Sub-task > Components: common > Affects Versions: 3.0.0-beta1 > Reporter: Haibo Chen > Assignee: Haibo Chen > Attachments: HADOOP-14957.prelim.patch > > -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
