Zoran Dimitrijevic created HDFS-12052:
-----------------------------------------
Summary: Set "SWEBHDFS delegation" as DT kind if ssl is enabled in
HttpFS
Key: HDFS-12052
URL: https://issues.apache.org/jira/browse/HDFS-12052
Project: Hadoop HDFS
Issue Type: Bug
Components: httpfs, webhdfs
Affects Versions: 3.0.0-alpha3, 2.7.3
Reporter: Zoran Dimitrijevic
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).
