Subject [jira] [Commented] (HADOOP-12549) Extend HDFS-7456 default generically to all pattern lookups
Date Wed, 26 Oct 2016 07:13:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15607688#comment-15607688

Harsh J commented on HADOOP-12549:

[~yzhangal] or [~aw] - Could you help review this one? The change should help some limited
form of clients that deal with multiple RM/KMS/etc. services (HDFS is already covered via
a hdfs-default.xml change, for the most classic use-case of DistCp).

>            Priority: Minor
>         Attachments: HADOOP-12549.patch
> In HDFS-7546 we added a hdfs-default.xml property to bring back the regular behaviour
of trusting all principals (as was the case before HADOOP-9789). However, the change only
targeted HDFS users and also only those that used the default-loading mechanism of Configuration
class (i.e. not {{new Configuration(false)}} users).
> I'd like to propose adding the same default to the generic RPC client code also, so the
default affects all form of clients equally.
