    Description

      After running about a dozen or so requests, the timelinereader log is filled with the following logging entries:

      2016-05-16 15:59:13,364 INFO org.apache.hadoop.yarn.server.timelineservice.storage.common.ColumnHelper: null prefix was specified; returning all columns

      There were some ~ 3,000 such logging entries. It's too excessive.
