Question

OOZIE字数示例给出了JA009：RPC响应超出了最大数据长度。我们已经将ipc.maximum.data.length加倍，并重新启动了NameNode。

您是否尝试修改hdfs-site.xml中的配置？

<property>
     <name>ipc.maximum.data.length</name>
     <value>134217728</value>
</property>

如果已经足够高，请确保fs.default.name的core-site.xml配置使用的是IP，而不仅仅是本地主机。

<configuration>
       ....
        <property>
                <name>fs.default.name</name>
                <value>hdfs://your ip:9000</value>
        </property>
</configuration>
