Hi Alexis, Gavin,
Thanks very much for your kind comment.My spark command is :
spark-submit --class com.zyyx.spark.example.LinearRegression --master
yarn-client LinearRegression.jar
Both spark-shell and spark-submit will not run, all is hanging during the stage,
15/09/27 19:18:06 INFO yarn.Client: Application report for
application_1440676456544_0727 (state: ACCEPTED)...
The more deeper error log under /hdfs/yarn/logs/:
15/09/27 19:10:37 INFO util.Utils: Successfully started service 'sparkYarnAM'
on port 53882.
15/09/27 19:10:37 INFO yarn.ApplicationMaster: Waiting for Spark driver to be
reachable.
15/09/27 19:10:37 ERROR yarn.ApplicationMaster: Failed to connect to driver at

15/09/27 19:10:37 ERROR yarn.ApplicationMaster: Failed to connect to driver at
127.0.0.1:39581, retrying ...
For the all machine nodes, I just installed hadoop and spark, with same path &
file & configuration, and
copied one of the hadoop & spark directory to the remote gateway machine, the
all would be with same
path & file name & configuration under different nodes.
In the link Running Spark on YARN - Spark 1.5.0 Documentation, there is some
words as:Ensure that HADOOP_CONF_DIR or YARN_CONF_DIR points to the directory
which contains the (client side) configuration files for the Hadoop
cluster.These configs are used to write to HDFS and connect to the YARN
ResourceManager.
I do not exactly catch the first sentence.
hadoop version is 2.5.2, spark version is 1.4.1
The spark-env.sh setting,
export SCALA_HOME=/usr/lib/scala
export JAVA_HOME=/usr/java/jdk1.7.0_45
export R_HOME=/usr/lib/r
export HADOOP_HOME=/usr/lib/hadoop
export YARN_CONF_DIR=/usr/lib/hadoop/etc/hadoop
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export SPARK_MASTER_IP=master01
#export SPARK_LOCAL_IP=master02
export SPARK_LOCAL_IP=localhost
export SPARK_LOCAL_DIRS=/data/spark_local_dir
Would you help point out what is wrong place I made...I must show sincere
appreciation towards your help.
Best Regards,Zhiliang

It is working, We are doing the same thing everyday. But the remote server
needs to able to talk with ResourceManager.
If you are using Spark-submit, your will also specify the hadoop conf
directory in your Env variable. Spark would rely on that to locate where the
cluster's resource manager is.
I think this tutorial is pretty clear:

Hi Yue,
Thanks very much for your kind reply.
I would like to submit spark job remotely on another machine outside the
cluster,and the job will run on yarn, similar as hadoop job is already done,
could youconfirm it could exactly work for spark...
Do you mean that I would print those variables on linux command side?

Hi All,
I would like to submit spark job on some another remote machine outside the
cluster,I also copied hadoop/spark conf files under the remote machine, then
hadoopjob would be submitted, but spark job would not.
In spark-env.sh, it may be due to that SPARK_LOCAL_IP is not properly set,or
for some other reasons...
This issue is urgent for me, would some expert provide some help about this
problem...
I will show sincere appreciation towards your help.
Thank you!Best Regards,Zhiliang

Hi all,
The spark job will run on yarn. While I do not set SPARK_LOCAL_IP any, or just
set asexport SPARK_LOCAL_IP=localhost #or set as the specific node ip on
the specific spark install directory
It will work well to submit spark job on master node of cluster, however, it
will fail by way of some gateway machine remotely.
The gateway machine is already configed, it works well to submit hadoop job.It
is set as:
export SCALA_HOME=/usr/lib/scala
export JAVA_HOME=/usr/java/jdk1.7.0_45
export R_HOME=/usr/lib/r
export HADOOP_HOME=/usr/lib/hadoop
export YARN_CONF_DIR=/usr/lib/hadoop/etc/hadoop
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export SPARK_MASTER_IP=master01
#export SPARK_LOCAL_IP=master01 #if no SPARK_LOCAL_IP is set, SparkContext
will not start
export SPARK_LOCAL_IP=localhost #if localhost is set, SparkContext is
started, but failed later
export SPARK_LOCAL_DIRS=/data/spark_local_dir
...
The error messages:
15/09/25 19:07:12 INFO util.Utils: Successfully started service 'sparkYarnAM'
on port 48133.
15/09/25 19:07:12 INFO yarn.ApplicationMaster: Waiting for Spark driver to be
