Modification method

Modify the hadoop2.7.7 directory on the hadoop namenode node

Cd ~ / hadoop-2.7.7/etc/hadoop/

Configuration

[hadoop@namenodeyw hadoop] $cat masters

Datenodeyw1 # indicates that the SecondaryNameNode service will be started on this node

[hadoop@namenodeyw hadoop] $cat hdfs-site.xml dfs.http.address namenodeyw:50070 The address and the base port where the dfs namenode web ui will listen on. If the port is 0 then the server will start on a free port. Dfs.namenode.secondary.http-address datanodeyw1:50090 dfs.name.dir / opt/hadoop/dfs/name Path on the local filesystem where theNameNode stores the namespace and transactions logs persistently. Dfs.data.dir / opt/hadoop/dfs/data Comma separated list of paths on the localfilesystem of a DataNode where it should store its blocks. Dfs.replication 3 dfs.permissions false need not permissions

[hadoop@namenodeyw hadoop] $cat core-site.xml

Hadoop.tmp.dir / opt/hadoop/tmp Abase for other temporary directories. Fs.default.name hdfs://namenodeyw:9000 fs.checkpoint.period 3600 The number of seconds between two periodic checkpoints. Fs.checkpoint.size 67108864

Then synchronize the changed configuration file directory to other nodes.

Restart the service in turn.

Restart the hadoop machine first. / start-all.sh

Restart zookeeper. / zkSever.sh start

Then start habase. / start-hbase.sh on the configuration hbase master node

Start on namenode
