我正在使用cdh5.1构建一个原型。我使用的是3节点集群。将数据从数据库上载到hdfs时，资源管理器服务器意外中止。现在我在hdfs中看到一个大小为3gb的文件。
问题：
数据库中用于查询的总行数为42600000。传输7641242行后，服务器停止。我在用talend做etl。我知道这一次除了重新开始这个过程之外，我将无能为力。
我们有没有办法在将来缓解这个问题？
运行dfsadmin命令后更新：

sudo -u hdfs hadoop dfsadmin -report
DEPRECATED: Use of this script to execute hdfs command is deprecated.
Instead use the hdfs command for it.
