- Cloudera Manager 5
Cloudera Manager is installed in the VM but is turned off
by default. If you would like to use Cloudera Manager, click
on the Launch Cloudera
Manager icon on the desktop. It is strongly
recommended that before you do so, you configure the VM with
8 GB of RAM and 2 virtual CPU cores (by default it will use
4 GB of RAM and 1 virtual CPU core). Cloudera Manager and
all of the CDH services may not launch properly with less
RAM. After launching Cloudera Manager, all of the services
in CDH will be started, although it may take several minutes
for Cloudera Manager to start all of the services in order.
To conserve resources and improve performance, it is
recommended that you stop services you do not plan to use.
Changes made to configuration files before launching
Cloudera Manager will not be preserved.
You can start or reconfigure any
installed services using the web interface that is
automatically displayed when the VM starts. Standard CDH 5
command-line tools are available for use, as well.
See Cloudera Manager, installation,
configuration, and usage instructions in the Cloudera Manager 5 documentation.

part of the boot process, the VM automatically launches
Cloudera Manager and configures HDFS, Hive, Hue, MapReduce,
Oozie, ZooKeeper, Flume, HBase, Cloudera Impala, Cloudera
Search, and YARN. Only the ZooKeeper, HDFS, MapReduce, Hive,
and Hue services are started automatically. Flume, HBase,
Oozie, Sqoop, Impala, Solr, and YARN services are not
started because they are not used in all cases and not
starting them conserves RAM.
