Does changing the block size of MiniDFSCluster work?

[Jason Rutherglen <ja...@gmail.com>]

I'm using the append 0.20.3 branch and am wondering why the following
fails, where setting the block size either in the Configuration or the
DFSClient.create method causes a failure later on when writing a file
out.

Configuration conf = new Configuration();
long blockSize = (long)32 * 1024 * 1024 * 1024;
conf.setLong("dfs.block.size", blockSize); // doesn't work
MiniDFSCluster cluster = new MiniDFSCluster(conf, 1, true, null);
FileSystem fileSys = cluster.getFileSystem();
fileSys.create(path, false, bufferSize, replication, blockSize); // doesn't work
fileSys.create(path); //works
