HDFSWrite写入文件createBlockOutputStream失败

经DataX智能分析,该任务最可能的错误原因是:
com.alibaba.datax.common.exception.DataXException: Code:[HdfsWriter-04], Description:[您配置的文件在写入时出现IO异常.]. - java.io.IOException: Connection reset by peer

I need some help.I get some exceptions from HDFSWrite task.
It show some errors. For example
1.Code[hdfswriter-04]
2.Exception in createBlockOutputStream
3.java.IO.Exception:connection reset by peer
4.java.io.exception: unable to create new block
5.could not get block location

In my opinion，It maybe related with createBlockOutputStream failure.
What should I do?
Thank you!!!

Start with the reported stack frames in HdfsHelper.java:317 and HdfsWriter.java:360, then trace into Hadoop DFSOutputStream.DataStreamer.createBlockOutputStream. Compare the DataX configuration and client logs with the HDFS service-side logs for the connection reset and block-location errors. Done means identifying a reproducible cause and documenting or validating a concrete resolution; the issue currently provides no test or reproduction details.
