-------------------------------------
Summary: Getting some error while increasing the hadoop cluster size.
Key: HADOOP-10180
URL: https://issues.apache.org/jira/browse/HADOOP-10180
Project: Hadoop Common
Issue Type: Task
Reporter: Ravi Hemnani
Priority: Trivial
We have a 5-node hadoop cluster and we are trying to increase the size of the cluster. We have added 2 new disks to each of the 5-boxes and we followed all the steps of putting the disk to the hadoop cluster. Everything works fine except when we restart a datanode, there are errors multiple times in the log file. Following is the error which appears in the log files,
2013-12-23 14:32:19,406 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: DatanodeRegistration(172.16.200.128:50010, storageID=DS-1937554000-172.16.200.128-50010-1376068931321, infoPort=50075, ipcPort=50020):DataXceiver
