Subject [jira] [Updated] (HDFS-4548) Webhdfs doesn't renegotiate SPNEGO token
Date Wed, 27 Mar 2013 20:43:15 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Daryn Sharp updated HDFS-4548:

    Attachment: HDFS-4548.patch

Same as previous patches, just made from the top level instead of 1 dir deep.  Tests aren't
feasible due to kerberos being required to activate code paths, but fixes have been verified
on internal clusters blocked by this issue.

> When the webhdfs SPNEGO token expires, the fs doesn't attempt to renegotiate a new SPNEGO
token.  This renders webhdfs unusable for daemons that are logged in via a keytab which would
allow a new SPNEGO token to be generated.
