Zhang, Liye created SPARK-7865:
----------------------------------
Summary: Hadoop Filesystem for eventlog closed before sparkContext
stopped
Key: SPARK-7865
URL: https://issues.apache.org/jira/browse/SPARK-7865
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.4.0
Reporter: Zhang, Liye
After [SPARK-3090|https://issues.apache.org/jira/browse/SPARK-6986] (patch
[#5969|https://github.com/apache/spark/pull/5696]), SparkContext will be
automatically stop if user forget to.
While when shutdownhook is called, Eventlog will give out following exception
for flushing content:
