> If hostname of flume agent is uppercase or mixed-case，web client will not
> show flume metrics normally.
> This is because we will query metric records by lowercase hostname used in
> ambari ,but the hostname in METRIC_RECORD is not lowercase (see attached
> picture),so we will not get any records.This patch amis to convert hostname
> of metric record of flume to lowercase before inserting into ams hbase.
