Akira Ajisaka updated HDFS-12863:
---------------------------------
Description: In ContainerReportManagerImpl.java,
{{OzoneClientUtils.getScmHeartbeatInterval(config)}} is called for each
container report. We should cache the interval and avoid calling
{{Configuration.get(name)}}. (was: In DataNode daemon log, the following info
message is displayed every 30 seconds:
{noformat}
2017-11-28 12:19:52,127 INFO org.apache.hadoop.conf.Configuration.deprecation:
No unit for ozone.scm.heartbeat.interval.seconds(30) assuming SECONDS

The message should be displayed once.)
