Aaron T. Myers updated HADOOP-7229:
-----------------------------------
Release Note: When Hadoop's Kerberos integration is enabled, it is now
required that either {{kinit}} be on the path for user accounts running the
Hadoop client, or that the {{hadoop.kerberos.kinit.command}} configuration
option be manually set to the absolute path to {{kinit}}. (was: It is now
required that either {{kinit}} be on the path for user accounts running the
Hadoop client, or that the {{hadoop.kerberos.kinit.command}} configuration
option be manually set to the absolute path to {{kinit}}.)
Per an offline suggestion from Eli, I'm amending the release note to make it
clear that this is only necessary to configure when security is enabled.
