Li Bo commented on HDFS-7889:
-----------------------------
Thanks for Zhe’s review and update of the patch.
bq. we can subclass DataStreamer to achieve this.
I think that’s also a good solution to help implement striped output stream.
New patch includes {{StripedDataStreamer}}.
bq. However that will lead to another big change to DFSOutputStream
The problem is we need get HdfsFileStatus to see if the file is striped
layout. Currently I put the “if” logic in {{DFSOutputStream#newStream}} in
patch 004.
