I use hadoop2.2.0 , I start hadoop-daemon service,like follows: [hdfs@localhost logs]$ hadoop-daemon.sh start namenode [hdfs@localhost logs]$ hadoop-daemon.sh start secondarynamenode [hdfs@localhost logs]$ hadoop-daemon.sh start datanode [hdfs@localhost logs]$ jps 4135 NameNode 4270 SecondaryNameNode 4331 DataNode 4364 Jps
After a while,when I use jps command,I find datanode is disappeared.Why? [hdfs@localhost logs]$ jps 4135 NameNode 4270 SecondaryNameNode 4364 Jps --------------------------------------------------------------------------------------------------- Confidentiality Notice: The information contained in this e-mail and any accompanying attachment(s) is intended only for the use of the intended recipient and may be confidential and/or privileged of Neusoft Corporation, its subsidiaries and/or its affiliates.
