Paul Lin updated FLINK-11135:
-----------------------------
Description: Currently, Hadoop config search order is: `HADOOP_HOME >
HADOOP_CONF_DIR > Flink configuration entries`. However, YARN client prefers
`HADOOP_CONF_DIR` to `HADOOP_HOME`, so it would result in inconsistency if the
two env variables point to different paths. Hence I propose to refactor the
Hadoop config loading in HadoopUtils, changing the search order to
`HADOOP_CONF_DIR > Flink configuration entries > HADOOP_HOME`. (was:
