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). -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
