Hi all,
We're trying to submit a python file, pi.py in this case, to yarn from java
code but this kept failing(1.6.0).
It seems the AM uses the arguments we passed to pi.py as the driver IP
address.
Could someone help me figuring out how to get the job done. Thanks in
advance.
The java code looks like below:
String[] args = new String[]{
"--name",
"Test Submit Python To Yarn From Java",
"--primary-py-file",
SPARK_HOME + "/examples/src/main/python/pi.py",
"--num-executors",
"5",
"--driver-memory",
"512m",
"--executor-memory",
"512m",
"--executor-cores",
"1",
"--arg",
args[0]
};
Configuration config = new Configuration();
SparkConf sparkConf = new SparkConf();
ClientArguments clientArgs = new ClientArguments(args, sparkConf
);
Client client = new Client(clientArgs, config, sparkConf);
client.run();
The jar is submitted by spark-submit::
./bin/spark-submit --class SubmitPyYARNJobFromJava --master yarn-client
TestSubmitPythonFromJava.jar 10
The job submit to yarn just stay in ACCEPTED before it failed
What I can't figure out is, yarn log shows AM couldn't reach the driver at
10:0, which is my argument passed to pi.py
