Kengo Seki created HADOOP-12072:
-----------------------------------
Summary: conftest raises a false alarm over the fair scheduler
configuration file
Key: HADOOP-12072
URL: https://issues.apache.org/jira/browse/HADOOP-12072
Project: Hadoop Common
Issue Type: Bug
Reporter: Kengo Seki
hadoop conftest subcommand validates the XML files in ${HADOOP_CONF_DIR} by
default, and assumes the root element of the XML is <configuration>.
But it is popular to put the fair scheduler configuration file as
${HADOOP_CONF_DIR}/fair-scheduler.xml, and its root element is <allocations>,
so conftest raises a false alarm.
