> Key: IGNITE-6747
> URL: https://issues.apache.org/jira/browse/IGNITE-6747
> Project: Ignite
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Components: hadoop
> Affects Versions: 2.2
> Reporter: Reid Chan
>
> So far, igfs can access to kerberized hdfs by providing {{keyTab}} and
> {{keyTabPrincipal}}:
> {code}
> <property name="keyTab" value="/path/to/keytab"/>
> <property name="keyTabPrincipal"
> value="ignite/fully.qualified.domain.name@REALM"/>
> {code}
> But it becomes nightmare when number of grid nodes is more than hundreds or
> even thousands which is in my case, since i have to configure FDQN for each
> node.
> Hadoop's package already provides an easy way which uses "_HOST" instead of
> FDQN, i think it's better to use it.
> Suggestions are welcomed.
