cdh3客户端与Apache Hadoop服务器0.20.xx互操作？ [英] cdh3 client interoperable with apache hadoop server 0.20.xx?

问题描述

我们有一个基于java客户端的 hadoop-core-0.20.2-cdh3u1.jar 。
对于运行Apache分布式0.20.xx的服务器（集群）工作是否安全？
或者cloudera会破坏一些apache API吗？

we have a hadoop-core-0.20.2-cdh3u1.jar based java client. Would it be safe to work against a server (cluster) running apache distributed 0.20.xx? Or did cloudera break some apache APIs?

谢谢

Thanks

推荐答案

可能是一个坏主意。尝试与使用hadoop核心版本 0.20.203.0 的客户端在使用cdh3u1的服务器上合作，并得到：

probably a bad idea. Tried working with a client using hadoop-core version 0.20.203.0 against a server with cdh3u1 and got:

org.apache.hadoop.ipc.RPC$VersionMismatch: 
Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 61, server = 63)

未尝试其他方式...

Didn't try the other way around...
