我使用Ambari安装了SCDF，但我似乎无法成功启动Spring Cloud Dataflow服务器。我从日志中获得以下输出：

根据日志，似乎问题与第51行的servers.yml中的配置有关，但我看不出它是什么错误。

编辑： 经过进一步审查，似乎该行中的servers.yml存在错误     yarnApplicationClasspath：{{hadoop_home}} / conf，{{hadoop_home}} / ，{{hadoop_home}} / lib / ，/ usr / hdp / current / hadoop-hdfs-client / ，的/ usr / HDP /电流/ Hadoop的HDFS的客户端/ LIB / ，在/ usr / HDP /电流/ Hadoop的纱线的客户端/ ，在/ usr / HDP /电流/ Hadoop的纱线的客户机/ LIB / ，在/ usr / HDP /电流/ EXT / hadoop的/ *

我编辑了该文件以替换{{hadoop_home}}变量，但似乎每次从ambari重新启动scdf服务器时它都会被覆盖。

1 个答案:

答案 0 :(得分：0)

确实yarnApplicationClasspath: {{hadoop_home}}看起来错了。

来源为yarnApplicationClasspath: {{yarn_app_classpath}}，价值来自yarn_app_classpath = config['configurations']['yarn-site']['yarn.application.classpath']。

你可以在ambari的纱线服务下查看yarn-site配置中的实际内容吗？

即我有类似

的东西 
<property>
  <name>yarn.application.classpath</name>
  <value>$HADOOP_CONF_DIR,/usr/hdp/current/hadoop-client/*,/usr/hdp/current/hadoop-client/lib/*,/usr/hdp/current/hadoop-hdfs-client/*,/usr/hdp/current/hadoop-hdfs-client/lib/*,/usr/hdp/current/hadoop-yarn-client/*,/usr/hdp/current/hadoop-yarn-client/lib/*</value>
</property>
