Barun Kumar updated LENS-1514: ------------------------------ Summary: Support HDFS delegation token authentication (was: Support HDFS delegation token suthentication) > Support HDFS delegation token authentication > -------------------------------------------- > > Key: LENS-1514 > URL: https://issues.apache.org/jira/browse/LENS-1514 > Project: Apache Lens > Issue Type: Improvement > Components: client, server > Reporter: Barun Kumar > Assignee: Barun Kumar > Priority: Major > > As part of LENS-1509, we have added Spnego authentication based on Kerberos > to lens. This will work in client-server mode. But this approach will cease > to work in a hadoop cluster in which user is using lens client in a mapred > job(such as oozie java action) since there will not be keytabs in the hadoop > cluster. The authentication in hadoop work on concept of delegation > token([https://blog.cloudera.com/blog/2017/12/hadoop-delegation-tokens-explained/).] > Here we are introducing delegation token auth in lens. We are piggybacking on > HDFS to do authentication by passing it's token and performing a filesystem > operation. > > We will add proper delegation token implementation as future improvement. > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
