Yang Wang created YARN-7647:
-------------------------------
Summary: NM print inappropriate error log when node-labels is
enabled
Key: YARN-7647
URL: https://issues.apache.org/jira/browse/YARN-7647
Project: Hadoop YARN
Issue Type: Bug
Reporter: Yang Wang
{code:title=NodeStatusUpdaterImpl.java}
... ...
if (response.getAreNodeLabelsAcceptedByRM() && LOG.isDebugEnabled()) {
LOG.debug("Node Labels {" + StringUtils.join(",", previousNodeLabels)
+ "} were Accepted by RM ");
} else {
// case where updated labels from NodeLabelsProvider is sent to RM and
// RM rejected the labels
LOG.error(
"NM node labels {" + StringUtils.join(",", previousNodeLabels)
+ "} were not accepted by RM and message from RM : "
+ response.getDiagnosticsMessage());
}
... ...
{code}
When LOG.isDebugEnabled() is false, NM will always print error log. It is an
obvious error and is so misleading.
