Run oozie manually "menas without hue"

it is also get the same error

user_154844160

delete exclude resources/hdfs-site.xml resources/core-site.xml in jar

user_154844160

i also have this issue, use oozie 5.2.1 and apache hadoop 2.10.1 this is caused by applicationmaster can't find hdfs-site.xml from classpath, when we use spark-submit it will add HADOOP_CONF_DIR to classpath

oozie also add it into classpath like $PWD:$PWD/:$HADOOP_CONF_DIR:$HADOOP_COMMON_HOME/share/hadoop/common/:......

but i find the environment variable 'HADOOP_CONF_DIR' oozie submit to rm is empty

check below code, it set HADOOP_CONF_DIR to HADOOP_CLIENT_CONF_DIR

 private void setHadoopConfDirIfEmpty(Map<String, String> env) {
    String envHadoopConfDir = env.get(HADOOP_CONF_DIR);
    if (StringUtils.isEmpty(envHadoopConfDir)) {
        String hadoopClientConfDirVariable = String.format("${%s}",HADOOP_CLIENT_CONF_DIR);
        LOG.debug("Setting {0} environment variable to {1}.", HADOOP_CONF_DIR, hadoopClientConfDirVariable);
        env.put(HADOOP_CONF_DIR, hadoopClientConfDirVariable);
    }
    else {
        LOG.debug( "Environment variable {0} is already set to {1}.", HADOOP_CONF_DIR, envHadoopConfDir);
    }
}

eventhrough i add env 'HADOOP_CLIENT_CONF_DIR' which the same value with HADOOP_CONF_DIR, i find the issue still not resolved, i have no idea, then i just find another way to specify the environment variable,

add follow configuratition in core-site.xml

<property>
    <name>oozie.launcher.env</name>
    <value>HADOOP_CONF_DIR=/usr/local/hadoop/hadoop-2.10.1/etc/hadoop/</value>
</property>

Finally, i solve the issue this way
