----------------------------------
Summary: DIGEST-MD5: Out of order sequencing of messages from
server
Key: SPARK-21495
URL: https://issues.apache.org/jira/browse/SPARK-21495
Project: Spark
Issue Type: Bug
Components: Shuffle, Spark Core
Affects Versions: 1.6.1
Environment: OS: RedHat 7.1 64bit
Spark: 1.6.1
Reporter: Xin Yu Pan
We hit an issue when enabling authentication and Sasl encryption, see bold font
in following parameter list.
spark.local.dir /tmp/xpan-spark-161
spark.eventLog.dir file:///home/xpan/spark-conf/event
spark.eventLog.enabled true
spark.history.fs.logDirectory file:/home/xpan/spark-conf/event
spark.history.ui.port 18085
spark.history.fs.cleaner.enabled true
spark.history.fs.cleaner.interval 1d
spark.history.fs.cleaner.maxAge 14d
spark.dynamicAllocation.enabled false
spark.shuffle.service.enabled false
spark.shuffle.service.port 7448
spark.shuffle.reduceLocality.enabled false
spark.master.port 7087
spark.master.rest.port 6077
spark.executor.extraJavaOptions -Djava.security.egd=file:/dev/./urandom
**spark.authenticate true
spark.authenticate.secret 5828d44b-f9b9-4033-b1f5-21d1e3273ec2
spark.authenticate.enableSaslEncryption false
spark.network.sasl.serverAlwaysEncrypt false**
We run the simple SparkPi example and there are Exception messages even though
the application gets done.
