我使用CDH 6.3.2
hadoop是HA
我用星星之火制作了一个工作流
运行这个工作流，我得到一个错误

我可以运行星星之弹--jars hdfs://nameservice1 1/sparklib/*..jar
"hadoop fs -ls /user“工作。
只是不适用于oozie
那么，如何才能修复it.someone可以帮助我。

我也有这个问题，使用oozie 5.2.1和apache 2.10.1这是由应用程序管理员无法从类路径中找到hdfs-site.xml造成的，当我们使用spark submit时，它将向类路径添加HADOOP_CONF_DIR。
oozie还将其添加到类路径中，如$PWD:$PWD/:$HADOOP_CONF_DIR:$HADOOP_COMMON_HOME/share/hadoop/common/:......
但是我发现环境变量'HADOOP_CONF_DIR‘oozie提交给rm是空的。
检查下面的代码，它将HADOOP_CONF_DIR设置为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);
}
}即使我添加了与HADOOP_CONF_DIR相同值的env‘HADOOP_CONF_DIR’，我仍然发现这个问题还没有解决，我不知道，然后我就找到了另一种方法来指定环境变量，
在core-site.xml中添加以下配置
<property>
<name>oozie.launcher.env</name>
<value>HADOOP_CONF_DIR=/usr/local/hadoop/hadoop-2.10.1/etc/hadoop/</value>
</property> 最后，我用这种方式解决了这个问题。
