Robert Metzger created FLINK-18160:
--------------------------------------
Summary: YARN session logs about HADOOP_CONF_DIR even though
HADOOP_CLASSPATH containing a config is set
Key: FLINK-18160
URL: https://issues.apache.org/jira/browse/FLINK-18160
Project: Flink
Issue Type: Improvement
Components: Deployment / YARN
Affects Versions: 1.11.0
Reporter: Robert Metzger
Flink prints
{code}
Setting HADOOP_CONF_DIR=/etc/hadoop/conf because no HADOOP_CONF_DIR was set.
{code}
When running Flink on YARN with the HADOOP_CLASSPATH set. "hadoop classpath"
also returns the configuration directory, so HADOOP_CONF_DIR is not needed
anymore.
I suggest to revisit this log message / behavior as it is misleading
