SPARK YARN：无法从客户端发送作业（org.apache.hadoop.ipc.Client-重试连接到服务器：0.0.0.0/0.0.0.0:8032）

Question

I'm trying to send spark job to yarn (without HDFS) in HA mode.

For submitting I'm using org.apache.spark.deploy.SparkSubmit . When I send request from machine with active Resource Manager, it works well. But if I' trying to send from machine with standby Resource Manager, job fails with error:

DEBUG org.apache.hadoop.ipc.Client - Connecting to spark2-node-dev/10.10.10.167:8032
DEBUG org.apache.hadoop.ipc.Client - Connecting to /0.0.0.0:8032
org.apache.hadoop.ipc.Client - Retrying connect to server: 0.0.0.0/0.0.0.0:8032. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep

However, when I send request via command line (spark-submit), it works well through both active and standby machine.

What can cause the problem?

PS Use the same parameters for both type of sending job: org.apache.spark.deploy.SparkSubmit and spark-submit command line request. And properties yarn.resourcemanager.hostname.rm_id defined for all rm hosts

Answer 1

The problem was with absence of yarn-site.xml within class path for spark-submitter jar. Actually spark submitter jar does not take to account YARN_CONF_DIR or HADOOP_CONF_DIR env var, so cannot see yarn-site.

One solution that I found was to put yarn-site into classpath of jar.
