Karthik Kambatla commented on HDFS-9780:
----------------------------------------
Quickly skimmed through the patch.
Do we want to checkForProperty even if security is not enabled?
{code}
// Validate config so that we don't get an NPE
checkForProperty(conf, KEYTAB_PROPERTY_KEY);
checkForProperty(conf, USERNAME_PROPERTY_KEY);
{code}
Once the patch is updated based on HDFS-9637, will take a closer look.
