[jira] [Created] (FLINK-29754) HadoopConfigLoader should consider Hadoop configuration files

Peter Vary created FLINK-29754:
----------------------------------

             Summary: HadoopConfigLoader should consider Hadoop configuration files
                 Key: FLINK-29754
                 URL: https://issues.apache.org/jira/browse/FLINK-29754
             Project: Flink
          Issue Type: Bug
          Components: FileSystems
            Reporter: Peter Vary


Currently [HadoopConfigLoader|https://github.com/apache/flink/blob/master/flink-filesystems/flink-hadoop-fs/src/main/java/org/apache/flink/runtime/util/HadoopConfigLoader.java] considers Hadoop configurations on the classpath, but does not consider Hadoop configuration files which are set in another way.

So if the Hadoop configuration is set through the {{HADOOP_CONF_DIR}} environment variable, then the configuration loaded by the HadoopConfigLoader will not contain the values set there.

This can cause unexpected behaviour when setting checkpoint / savepoint dirs on S3, and the specific S3 configurations are set in the Hadoop configuration files
