             Summary: Workaround for HDFS delegation token expiry broken with some Hadoop versions
                 Key: SPARK-21080
                 URL: https://issues.apache.org/jira/browse/SPARK-21080
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 2.1.0
         Environment: Spark 2.1.0 on Yarn, Hadoop 2.7.3
            Reporter: Lukasz Raszka
            Priority: Minor


We're getting struck by SPARK-11182, where the core issue in HDFS has been fixed in more recent versions. It seems that [workaround introduced by user SaintBacchus|https://github.com/apache/spark/commit/646366b5d2f12e42f8e7287672ba29a8c918a17d] doesn't work in newer version of Hadoop. This seems to be cause by a move of property name from {{fs.hdfs.impl}} to {{fs.AbstractFileSystem.hdfs.impl}} which happened somewhere around 2.7.0 or earlier. Taking this into account should make workaround work again for less recent Hadoop versions.
