-------------------------------------
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.
