Subject Re: sqoop import into secure Hbase with kerberos
Date Mon, 05 Aug 2013 21:29:47 GMT
There should be a password. You should have a keytab associated with that
principal, which would allow you to authenticate as that principal. See
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Security-Guide/CDH4-Security-Guide.htmlfor
more details on how that works.

A couple of things...
1. You need to make your kerberos credentials renewable. Right now it seems
like you cannot renew. See
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH4/latest/CDH4-Security-Guide/cdh4sg_topic_17.html
.
2. AES256 encryption is not inherently supported. Did you install support
for AES256?
