But it will cause security > concern to allow other service user in hadoop group to kinit hdfs headless > principal using hdfs.headless.keytab. In this way, other service user could > "pretend" to be hdfs user and be granted hdfs user's authorities. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
