Re: java.io.IOException: config() IMP
Hi,
I am using CDH3.
I need to stream huge amount of data from our application to hadoop.
I am opening a connection like
config.set("fs.default.name",hdfsURI);
FileSystem dfs = FileSystem.get(config);
String path = hdfsURI + connectionKey;
Path destPath = new Path(path);
logger.debug("Path -- " + destPath.getName());
outStream = dfs.create(destPath);
and keeping the outStream open for some time and writing continuously through it and then closing it.
But it is throwing

Could you explain how/where you're stuck?
That DEBUG log doesn't even seem like a valid throw; its just to get a
strace I believe.
