             Summary: Closing shuffle writers we swallow more important exception
                 Key: SPARK-3690
                 URL: https://issues.apache.org/jira/browse/SPARK-3690

 case e: Exception =>
        if (writer != null) {
          writer.stop(success = false)
        }
        throw e
{quote}

Exception in writer.stop() swallows the important one. Couldn't find the reason for problems for days. Look up in internet "java.io.FileNotFoundException: /local/hd2/yarn/local/usercache/epahomov/appcache/application_1411219858924_12991/spark-local-20140924225309-03f5/21/shuffle_4_12_147 (No such file or directory)" - there are plenty poor guys like me.
