Mingliang Liu commented on HDFS-9794:
-------------------------------------
Thanks for working on this, [~jingzhao]. Determined closing stripe streamers
seems good to me.
I have a plain question: do we need to fix {{DFSOutputStream}} as well? My
concern is that, besides {{checkStreamerFailures()}}, {{flushInternal()}} for
flushing the last "close" empty packet may also throw exception.
{quote}
// may be thrown if more than 3 streamers fail, or updatePipeline RPC

Minor nit: *3* is EC policy dependent. We may better use a generic term?
> Streamer threads may leak if failure happens when closing the striped
> outputstream
