OOZIE：JA009：RPC 响应超出最大数据长度

Question

OOZIE wordcount 示例给出 JA009：RPC 响应超出最大数据长度。我们将 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>

如果它已经足够高，那么确保 fs.default.name 的 core-site.xml 配置使用的是 ip 而不仅仅是 localhost。

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