mapreduce出现异常：Error: org.apache.hadoop.ipc.RemoteException(java.io.IOExc...

程序目的是将一个文件切分成多个文件，切分个数可以选择，切分数量少的时候正常运行，切分数量多的时候出现以下情况导致运行失败：

求帮忙解答！！

貌似是赋值数量超出了datanode数量
增加操作系统参数再试

sysctl fs.file-max=2048000
sysctl fs.nr_open=1024000
ulimit -Hn 409600
ulimit -Sn 204800

我试了一下还是不行，hadoop的配置文件里又没有相关配置项
