Lin Wen commented on HAWQ-845:
------------------------------
Hi, Matt,
HAWQ doesn't require HDFS owned by secured user in secure mode. But, the
secureduser must have read/write permission on HDFS data directory.
> Parameterize kerberos principal name for HAWQ
> ---------------------------------------------
>
> Key: HAWQ-845
> URL: https://issues.apache.org/jira/browse/HAWQ-845
> Project: Apache HAWQ
> Issue Type: Improvement
> Reporter: bhuvnesh chaudhary
> Assignee: Lei Chang
> Priority: Minor
> Fix For: 2.0.1.0-incubating
>
>
> Currently HAWQ only accepts the principle 'postgres' for kerberos settings.
> This is because it is hardcoded in gpcheckhdfs, we should ensure that it can
> be parameterized.
> Also, it's better to change the default principal name postgres to gpadmin.
> It will avoid the need of changing the the hdfs directory during securing the
> cluster to postgres and will avoid the need of maintaining postgres user.
