I'm new to Spark and I'm busy setting up a Spark Cluster with HA enabled.
When starting a spark shell for testing via: bash spark-shell --master yarn --deploy-mode client
I receive the following error (See full error bellow): file:/tmp/spark-126d2844-5b37-461b-98a4-3f3de5ece91b/__spark_libs__3045590511279655158.zip does not exist
The application is marked as failed on the yarn web app and no containers are started.
When starting a shell via: spark-shell --master local it opens without errors.
I have noticed that files are only being written to the tmp folder on the node where the shell is created.
Any help will be much appreciated. Let me know if more information is required.

This error was due to the config in the core-site.xml file.
Please note that to find this file your
HADOOP_CONF_DIRenv variable must be set.In my case I added
HADOOP_CONF_DIR=/opt/hadoop-2.7.3/etc/hadoop/to./conf/spark-env.sh
core-site.xml
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://master:9000</value>
</property>
</configuration>
If this endpoint is unreachable, or if Spark detects that the file system is the same as the current system, the lib files will not be distributed to the other nodes in your cluster causing the errors above.
In my situation the node I was on couldn't reach port 9000 on the specified host.
Debugging
Turn the log level up to info. You can do this by:
Copy ./conf/log4j.properties.template to ./conf/log4j.properties
In the file set log4j.logger.org.apache.spark.repl.Main = INFO
Start your Spark Shell as normal. If your issue is the same as mine, you should see an info message such as: INFO Client: Source and destination file systems are the same. Not copying file:/tmp/spark-c1a6cdcd-d348-4253-8755-5086a8931e75/__spark_libs__1391186608525933727.zip
This should lead you to the problem as it starts the train reaction that results from the missing files.
