hi,all Have you tried to find out a way to make data transformation between two hdfs cluster, which are the different version.
In our environment, one data in 0.20.*, and we want to migrate into 2.0.5(HA). I try to use distcp, but it occurs to rpc version dismatch. org.apache.hadoop.ipc.RemoteException: Server IPC version 8 cannot > communicate with client version 4 > Could anyone give me an efficient way to make it? Thanks. -- Bing Jiang weibo: http://weibo.com/jiangbinglover BLOG: www.binospace.com BLOG: http://blog.sina.com.cn/jiangbinglover Focus on distributed computing, HDFS/HBase
