Description

Currently if one closes an OutputStream obtained from FileSystem#create and then calls write(...) on that closed stream, the write will appear to succeed without error though no data will be written to HDFS. A subsequent call to close will also silently appear to succeed. We should make it so that attempts to write to closed streams fails fast.
