Subject [jira] [Commented] (ACCUMULO-3701) MapReduce jobs need to perform kerberos login before instantiating Job
Date Mon, 30 Mar 2015 19:44:52 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-3701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14387287#comment-14387287

Josh Elser commented on ACCUMULO-3701:
--------------------------------------

A workaround for this is to {{kinit}} before submitting the job (and is probably the reason
I didn't notice it in my local testing).

> [~billie.rinaldi] found another nice bug through testing out running a Continuous Verify
MapReduce job with Kerberos/SASL enabled. She provided a keytab and SASL was enabled in the
client conf, but when the job was submitted, it failed because there were no kerberos credentials.
> * Instantiate Job (caches currentUser which is nobody)
> * Login with keytab programmatically, get Accumulo delegation token
> * Job tries to get HDFS delegation token, and fails
> We need to ensure that a UGI login happens when a keytab is provided as an option *before*
a Job is created.
