> Project: Falcon
> Issue Type: Bug
> Reporter: Balu Vellanki
> Assignee: Balu Vellanki
> Fix For: trunk, 0.10
>
>
> For some users, Falcon server fails to perform any operations on workflow
> engine after the kerberos credentials expire. Falcon server periodically
> revalidates the credentials from keytab saying
> ugi.checkTGTAndReloginFromKeytab(), but this operation will not work when ugi
> belongs to proxy user. The relogin should be done on
> UserGroupInformation.getLoginUser() for the falcon credentials to be renewed.
> The error looks as follows.
> {code}
> falcon instance -list -type process -name procName
> log4j:WARN No appenders could be found for logger
> (org.apache.hadoop.security.authentication.client.KerberosAuthenticator).
> log4j:WARN Please initialize the log4j system properly.
> log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more
> info.
> ERROR: Bad
