Zoran Dimitrijevic updated HDFS-12052:
--------------------------------------
Attachment: HDFS-12052.05.patch
Removed unrelated style fixes from all but tests. I'll upload one more patch
which doesn't have any unrelated style fixes even in that file if needed.
Can you please comment about hadoop prefix and whether we want to fix that in
this patch or in a different patch?
> Set SWEBHDFS delegation token kind when ssl is enabled in HttpFS

> Key: HDFS-12052
> URL: https://issues.apache.org/jira/browse/HDFS-12052

> Affects Versions: 2.7.3, 3.0.0-alpha3

> When httpfs runs with httpfs.ssl.enabled it should return SWEBHDFS delegation
> tokens.
> Currently, httpfs returns WEBHDFS delegation "kind" for tokens regardless of
> whether ssl is enabled or not. If clients directly connect to renew tokens
> (for example, hdfs dfs) all works because httpfs doesn't check whether token
> kind is for swebhdfs or webhdfs. However, this breaks when yarn rm needs to
> renew the token for the job (for example, when running hadoop distcp). Since
> DT kind is WEBHDFS, rm tries to establish non-ssl connection to httpfs and
> fails.
> I've tested a simple patch which I'll upload to this jira, and it fixes this
> issue (hadoop distcp works).
