## Init && Test
|
||||||
|
|
||||||
|
In the first deploy, format dfs first
|
||||||
|
|
||||||
|
### stop cluster (in master)
|
||||||
|
`sbin/stop-yarn.sh`
|
||||||
|
`sbin/stop-dfs.sh`
|
||||||
|
|
||||||
|
### remove previous data (in all nodes)
|
||||||
|
clear all data in /tmp in all nodes
|
||||||
|
|
||||||
|
### format hdfs (in master)
|
||||||
|
```
|
||||||
|
bin/hadoop namenode -format
|
||||||
|
```
|
||||||
|
|
||||||
|
### start cluster (in master)
|
||||||
|
`sbin/start-dfs.sh`
|
||||||
|
`sbin/start-yarn.sh`
|
||||||
|
|
||||||
|
### Run a test job
|
||||||
|
|
||||||
|
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar grep input output 'dfs[a-z.]+'
|
||||||
|
|
||||||
|
Note: there is no such dir default, you can add data by
|
||||||
|
|
||||||
|
```
|
||||||
|
bin/hadoop dfs -mkdir -p /user/root/input
|
||||||
|
```
|
||||||
|
and
|
||||||
|
```
|
||||||
|
bin/hadoop dfs -put etc/hadoop/* /user/root/input
|
||||||
|
```
|
||||||
|
|
||||||
|
### monitor cluster in browser
