Todd Lipcon commented on HDFS-2011:
-----------------------------------
I'm working on merging this with HDFS-1073, and had one question: when do we
expect that an editlog stream would be closed twice? In 1073 there are some
extra asserts, so instead of ignoring the second close, it now throws
"java.io.IOException: Trying to use aborted output stream". I'm debating
whether to remove this exception like you've done in this patch, vs remove the
patch, since it seems like it might be indicative of a bug to close a stream
twice.
