我正在使用CDH 5.1构建原型。我正在使用3节点集群。 在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3 GB的文件。
问题：
查询的数据库中的总行数为42600000.服务器在传输7641242行后停止。我正在使用Talend来做ETL。我知道这次我除了重新开始这个过程之外别无能为力。
我们有办法在未来缓解这个问题吗？
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.
