jerryshao 93f92c0ed7 [SPARK-21475][CORE][2ND ATTEMPT] Change to use NIO's Files API for external shuffle service ... ## What changes were proposed in this pull request? This PR is the second attempt of #18684 , NIO's Files API doesn't override `skip` method for `InputStream`, so it will bring in performance issue (mentioned in #20119). But using `FileInputStream`/`FileOutputStream` will also bring in memory issue (https://dzone.com/articles/fileinputstream-fileoutputstream-considered-harmful), which is severe for long running external shuffle service. So here in this proposal, only fixing the external shuffle service related code. ## How was this patch tested? Existing tests. Author: jerryshao <sshao@hortonworks.com> Closes #20144 from jerryshao/SPARK-21475-v2.		2018-01-04 11:39:42 -08:00
