Sangjin Lee created YARN-5096:
---------------------------------
Summary: timelinereader has a lot of logging that's not useful
Key: YARN-5096
URL: https://issues.apache.org/jira/browse/YARN-5096
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelineserver
Affects Versions: YARN-2928
Reporter: Sangjin Lee
Priority: Minor
After running about a dozen or so requests, the timelinereader log is filled
with the following logging entries:
{noformat}
2016-05-16 15:59:13,364 INFO
org.apache.hadoop.yarn.server.timelineservice.storage.common.ColumnHelper: null
prefix was specified; returning all columns

{noformat}
There were some ~ 3,000 such logging entries. It's too excessive.
Also, when I requested YARN_CONTAINER with fields=ALL, I see the following logs:
{noformat}
WARN
org.apache.hadoop.yarn.server.timelineservice.storage.common.TimelineStorageUtils:
incorrectly formatted column name: it will be discarded
