------------------------------------
Summary: Suppress verbose log message in
BlockPlacementPolicyDefault
Key: HDFS-11054
URL: https://issues.apache.org/jira/browse/HDFS-11054
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Arpit Agarwal
Assignee: Chen Liang
We saw an instance where this log message was generated millions of times in a
short time interval, slowing the NameNode to a crawl. It can probably be
changed to log at DEBUG level instead.
{code}
if (cur == null) {
LOG.warn("No excess replica can be found. excessTypes: "+excessTypes+
". moreThanOne: "+moreThanOne+". exactlyOne: "+exactlyOne+".");
break;
}
{code}
