I'm running into an error when setting the DFS block size to be larger
than the default. The following code is used to create the test
cluster:
Configuration conf = new Configuration();
MiniDFSCluster cluster = new MiniDFSCluster(conf, 2, true, null);
FileSystem fileSys = cluster.getFileSystem();
org.apache.hadoop.ipc.RemoteException: java.io.IOException: File
/index/_0_0.tib could only be replicated to 0 nodes, instead of 1
