Cloudera Manager requires the following resources:
Disk Space - Cloudera Manager Server
5 GB on the partition hosting /var.
500 MB on the partition hosting /usr.
For parcels, the space required depends on the number of parcels you download to the Cloudera Manager Server and distribute to Agent hosts. You can download multiple parcels of the same product, of different versions and builds. If you are managing multiple clusters, only one parcel of a product/version/build/distribution is downloaded on the Cloudera Manager Server—not one per cluster. In the local parcel repository on the Cloudera Manager Server, the approximate sizes of the various parcels are as follows:
Cloudera Impala - 200 MB per parcel
Cloudera Search - 400 MB per parcel
Cloudera Management Service -The Host Monitor and Service Monitor databases are stored on the partition hosting /var. Ensure that you have at least 20 GB available on this partition. By default unpacked parcels are located in /opt/cloudera/parcels.
RAM - 4 GB is recommended for most cases and is required when using Oracle databases. 2 GB may be sufficient for non-Oracle deployments with fewer than 100 hosts. However, to run the Cloudera Manager Server on a machine with 2 GB of RAM, you must tune down its maximum heap size (by modifying -Xmx in /etc/default/cloudera-scm-server). Otherwise the kernel may kill the Server for consuming too much RAM.
Python - Cloudera Manager and CDH 4 require Python 2.4 or higher, but Hue in CDH 5 and package installs of CDH 5 require Python 2.6 or 2.7. All supported operating systems include Python version 2.4 or higher.
Perl - Cloudera Manager requires perl.
