Subject [jira] [Commented] (HADOOP-14104) Client should always ask namenode for kms provider path.
Date Tue, 14 Nov 2017 18:19:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16251874#comment-16251874
] 

Xiao Chen commented on HADOOP-14104:
------------------------------------

Right, 2 separate clusters, running with the same {{fs.defaultFS}}, e.g. {{hdfs://nameservice1}}.
That creative application is the only one that does cross cluster work.

> Client should always ask namenode for kms provider path.

> According to current implementation of kms provider in client conf, there can only be
one kms.
> In multi-cluster environment, if a client is reading encrypted data from multiple clusters
it will only get kms token for local cluster.
> Not sure whether the target version is correct or not.
