Subject [jira] [Updated] (HADOOP-13856) FileSystem.rename(final Path src, final Path dst, final Rename... options) to become public; specified, tested
Date Fri, 02 Dec 2016 19:34:58 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13856?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mingliang Liu updated HADOOP-13856:
-----------------------------------
    Target Version/s: 2.8.0, 3.0.0-alpha2
         Component/s:     (was: fs/s3)
                      fs

+1 for the proposal.

I set the components as "fs" and target versions "2.8.0+". Correct me if I'm wrong.

> A lot of code within Hadoop (e.g. committers, filesystem) and downstream (Hive, spark),
don't know what to do when rename() returns false, as it can be a sign of nothing important,
or something major.
> In contrast, {{rename(final Path src, final Path dst, final Rename... options)}} has
stricter semantics and throws up all exceptions to be caught or relayed by callers. Yet it
cannot be used as its scoped at {{protected}} and tagged as {{@Deprected}}. 
> If it was made public then it could be used in committers and elsewhere; if we backport
the making of it public, then life will be even better
