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
