I have an HDFS cluster, version 2.7.2, with two namenodes and three datanodes. While uploads the file, an exception is found: java.io.IOException: Got error,status message,ack with firstBadLink as X:50010. I noticed that the datanode log is stopped, only datanode.log.1, not datanode.log. But the rest of the process logs are normal. The HDFS log directory is out of space. I did nothing but restart all the datanodes, and HDFS was back to normal. What's the reason? 从 Windows 版邮件发送 |
