Re: hadoop 2.2.0 cluster setup error : could only be replicated to 0 nodes instead of minReplication (=1)
Hi Can one of the implementors comment on what conditions trigger this error ? All the data nodes show up as commissioned. No errors during startup If I google for this error, there are several posts reporting the issue : but most of the answers have weak solutions like reformating and restarting none of which help. My guess is that this is a networking /port access issue. If anyone can shed light on what conditions cause this error , it would be much appreciated. regards On Mon, Feb 24, 2014 at 1:07 PM, Manoj Khangaonkar wrote: > Hi, > > I setup a cluster with > > machine1 : namenode and datanode > machine 2 : data node > > A simple hdfs copy is not working.

Re: hadoop 2.2.0 cluster setup error : could only be replicated to 0 nodes instead of minReplication (=1)
Generally, this is caused by insufficient space. please check the total capacity of your cluster and used, remaining ratio, and check dfs.datanode.du.reserved in the hdfs-site.xml if this value is larger than your remained capacity, then you got this Exception.
