Yongjun Zhang commented on HDFS-6312: ------------------------------------- HI [~daryn], I filed HDFS-6510 for the same issue and [~wheat9] sent me here (thanks Haohui). I wonder if we can dedicate this jira for this particular issue instead of bundling with other fix? Thanks. > WebHdfs HA failover is broken on secure clusters > ------------------------------------------------ > > Key: HDFS-6312 > URL: https://issues.apache.org/jira/browse/HDFS-6312 > Project: Hadoop HDFS > Issue Type: Bug > Components: webhdfs > Affects Versions: 3.0.0, 2.4.0 > Reporter: Daryn Sharp > Assignee: Daryn Sharp > Priority: Blocker > > When webhdfs does a failover, it blanks out the delegation token. This will > cause subsequent operations against the other NN to acquire a new token. > Tasks cannot acquire a token (no kerberos credentials) so jobs will fail. -- This message was sent by Atlassian JIRA (v6.2#6252)
