Jitendra Nath Pandey updated HDFS-1364: --------------------------------------- Attachment: HDFS-1364.2.patch > HFTP client should support relogin from keytab > ---------------------------------------------- > > Key: HDFS-1364 > URL: https://issues.apache.org/jira/browse/HDFS-1364 > Project: Hadoop HDFS > Issue Type: Bug > Components: security > Reporter: Kan Zhang > Assignee: Jitendra Nath Pandey > Attachments: HDFS-1364-y20.1.patch, HDFS-1364-y20.2.patch, > HDFS-1364.1.patch, HDFS-1364.2.patch > > > If a user starts a long-running HFTP client using a keytab, we should do > relogin automatically whenever TGT expires. Currently, HFTP client uses TGT > to fetch a delegation token and cache that delegation token for HFTP > operations. The delegation token is automatically renewed/refetched using > TGT. However, when TGT expires, delegation token renewal/refetch will fail > and no further HFTP operation is possible. This is unsatisfactory since the > user has given us her keytab. We should be able to relogin from keytab and > continue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
