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

             Summary: Consider {{env.hadoop.conf.dir}} when looking for the hadoop configuration
                 Key: FLINK-22414
                 URL: https://issues.apache.org/jira/browse/FLINK-22414
             Project: Flink
          Issue Type: Bug
          Components: Deployment / YARN, Runtime / Configuration
    Affects Versions: 1.12.2, 1.11.3, 1.13.0, 1.14.0
            Reporter: Matthias


The option of setting {{env.hadoop.conf.dir}} is allowed to be used as an alternative to setting the environment variable {{HADOOP_CONF_DIR}} based [on the documentation|https://ci.apache.org/projects/flink/flink-docs-stable/deployment/config.html#env-hadoop-conf-dir].

But the variable is not checked when determining the configuration location in the code (see [HadoopUtils.getHadoopConfiguration|https://github.com/apache/flink/blob/ba027e0b3e2cf950cd0bd7fb4f632a9c3449d9ad/flink-filesystems/flink-hadoop-fs/src/main/java/org/apache/flink/runtime/util/HadoopUtils.java#L53]).

This issue is about adding {{env.hadoop.conf.dir}} as an option to specify the Hadoop configuration directory.
