To bring the cluster up for the first time (disclaimer: independent execution of Puppet recipes on the cluster's nodes will automatically create HDFS structures and bring-up the services if all dependencies are satisfied, e..g configs are created, packages are installed, etc. If Puppet reports errors you might need to do the manual startup):
1) As root, run
...
| Code Block | ||
|---|---|---|
| ||
# /etc/init.d/hadoop-hdfs-namenode init (omit unless you want to star with nothing in your HDFS) |
...
# |
...
/etc/init.d/hadoop-hdfs-namenode start |
...
# /etc/init.d/hadoop-hdfs-datanode start |
...
# |
...
/usr/lib/hadoop/libexec/init-hdfs.sh (not needed after the first run) |
...
# /etc/init.d/hadoop-yarn-resourcemanager start |
...
# |
...
/etc/init.d/hadoop-yarn-proxyserver start |
...
# |
...
/etc/init.d/hadoop-yarn-nodemanager start |
on the master node.
2) On each of the slave nodes, run
...
| Code Block | ||
|---|---|---|
| ||
# /etc/init.d/hadoop-hdfs-datanode start |
...
# |
...
/etc/init.d/hadoop-yarn-nodemanager start |
...
To bring the cluster down cleanly:
1) On each of the slave nodes, run
...
| Code Block | ||
|---|---|---|
| ||
# /etc/init.d/hadoop-yarn-nodemanager stop |
...
# |
...
/etc/init.d/hadoop-hdfs-datanode stop |
2) On the master, run
...
| Code Block | ||
|---|---|---|
| ||
# /etc/init.d/hadoop-yarn-nodemanager stop |
...
# /etc/init.d/hadoop-yarn-proxyserver stop |
...
# |
...
/etc/init.d/hadoop-yarn-resourcemanager stop |
...
# |
...
/etc/init.d/hadoop-hdfs-datanode stop |
...
# |
...
/etc/init.d/hadoop-hdfs-namenode |
...
stop |
