Set up and tear down a Hadoop cluster.
|
|
|
|
This depends on either having ceph installed prior to hadoop, like so:
|
|
|
|
roles:
|
|
- [mon.0, mds.0, osd.0, hadoop.master.0]
|
|
- [mon.1, osd.1, hadoop.slave.0]
|
|
- [mon.2, hadoop.slave.1]
|
|
|
|
tasks:
|
|
- ceph:
|
|
- hadoop:
|
|
|
|
Or if you want to use HDFS under Hadoop, this will configure Hadoop
|
|
for HDFS and start it along with MapReduce. Note that it does not
|
|
require Ceph be installed.
|
|
|
|
roles:
|
|
- [hadoop.master.0]
|
|
- [hadoop.slave.0]
|
|
- [hadoop.slave.1]
|
|
|
|
tasks:
|
|
- hadoop:
|
|
hdfs: True
|
|
|
|
This task requires exactly one hadoop.master be specified
|
|
and at least one hadoop.slave.
|
|
|
|
This does *not* do anything with the Hadoop setup. To run wordcount,
|
|
you could use pexec like so (after the hadoop task):
|
|
|
|
- pexec:
|
|
hadoop.slave.0:
|
|
- mkdir -p /tmp/hadoop_input
|
|
- wget http://ceph.com/qa/hadoop_input_files.tar -O /tmp/hadoop_input/files.tar
|
|
