Sorry for the delay. What is the default filesystem on your HDFS setup? It
looks like its set to file: rather then hdfs://. That is the only reason I can
think its listing the directory as
file:/home/work/.sparkStaging/application_1384588058297_0056. Its basically
just copying it local rather then uploading to hdfs and its just trying to use
the local
file:/home/work/guojiacheng/spark/assembly/target/scala-2.9.3/spark-assembly-0.9.0-incubating-SNAPSHOT-hadoop2.0.5-alpha.jar.
It generally would create that in hdfs so it accessible on all the nodes. Is
your /home/work nfs mounted on all the nodes?
You can find the default fs by looking at the Hadoop config files. Generally
in core-site.xml. its specified by: <name>fs.default.name</name>
Its pretty odd if those are its erroring with file:// when you specified
hdfs://.
when you tried the hdfs:// did you upload both the spark jar and your client
jar (SparkAUC-assembly-0.1.jar)? If not try that and make sure to put hdfs://
on them when you export SPARK_JAR and specify the --jar option.
I'll try to reproduce the error tomorrow to see if a bug was introduced when I
added the feature to run spark from HDFS.

Hi Tom,
I'm on Hadoop 2.05. I can launch application spark 0.8 release normally.
However I switch to git master branch version with application built with it, I
got the jar not found exception and same happens to the example application. I
have tried both file:// protocol and hdfs:// protocol with jar in local file
system and hdfs respectively, and even tried jar list parameter when new spark
context. The exception is slightly different for hdfs protocol and local file
path. My application launch command is
SPARK_JAR=/home/work/guojiacheng/spark/assembly/target/scala-2.9.3/spark-assembly-0.9.0-incubating-SNAPSHOT-hadoop2.0.5-alpha.jar
/home/work/guojiacheng/spark/spark-class org.apache.spark.deploy.yarn.Client
--jar
/home/work/guojiacheng/spark-auc/target/scala-2.9.3/SparkAUC-assembly-0.1.jar
--class myClass.SparkAUC --args -c --args yarn-standalone --args -i --args
hdfs://{hdfs_host}:9000/user/work/guojiacheng/data --args -m --args
hdfs://{hdfs_host}:9000/user/work/guojiacheng/model_large --args -o --args
hdfs://{hdfs_host}:9000/user/work/guojiacheng/score --num-workers 60
--master-memory 6g --worker-memory 7g --worker-cores 1
And my build command is SPARK_HADOOP_VERSION=2.0.5-alpha SPARK_YARN=true
sbt/sbt assembly
Only thing I can think of might be related is on each cluster node, it has a
env SPARK_HOME point to a copy of 0.8 version's position, and its bin fold is
in Path environment variable. And 0.9 version is not there. It was something
left over, when cluster was setup. But I don't know whether it is related, as
my understand is the yarn version try to distribute spark through yarn.
