--------------------------------------

             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
