Reid Chan updated IGNITE-6747:
------------------------------
Description:
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:
{code}
<property name="keyTabPrincipal" value="ignite/_HOST@REALM"/>
{code}
and the "_HOST" will be replaced with respective machine's host name.
Suggestions are welcomed.
