Parcel Configuration Settings
You can configure where parcels are stored on the Cloudera Manager Server host, the URLs of parcel repositories, the properties of a proxy server through which parcels are downloaded, and where parcels distributed to cluster hosts are stored.
Configuring Cloudera Manager Server Parcel Settings
Minimum Required Role: Cluster Administrator (also provided by Full Administrator) This feature is not available when using Cloudera Manager to manage Data Hub clusters.
- Use one of the following methods to open the parcel settings page:
-
Navigation bar
- Click the parcel icon in the top navigation bar or click Hosts and click the Parcels tab.
- Click the Configuration button.
-
Menu
- Select .
- Select .
-
Navigation bar
- Specify a property:
- Local Parcel Repository Path defines the path on the Cloudera Manager Server host where downloaded parcels are stored.
-
Remote Parcel Repository URLs is
a list of repositories that Cloudera Manager checks for parcels.
Initially this points to the latest released CDH 5 and CDH
6repositories, but you can add your own repository locations to
the list. Use this mechanism to add Cloudera repositories that are
not listed by default, such as older versions of CDH. You can also
use this to add your own custom repositories. The locations
of the Cloudera parcel repositories are
https://archive.cloudera.com/product/parcels/version
, where product is a product name and version is a specific product version,latest
, or the substitution variable{latest_supported}
. The substitution variable appears after the parcel for the CDH version with the same major number as the Cloudera Manager version to enable substitution of the latest supported maintenance version of CDH.To add a parcel repository:- In the Remote Parcel Repository URLs list, click the addition symbol to open an additional row.
- Enter the path to the repository.
- Click Save Changes.
- Set the frequency with which Cloudera Manager checks for new parcels.
- Configure a proxy to access to the remote repositories.
- Configure whether downloads and distribution of parcels should occur automatically when new ones are detected. If automatic downloading and distribution are not enabled (the default), go to the Parcels page to initiate these actions.
- Control which products can be downloaded if automatic downloading is enabled.
- Control whether to retain downloaded parcels.
- Control whether to retain old parcel versions and how many parcel versions to retain
- Theoretically, the concurrent upload count (Maximum Parcel Uploads) is unimportant if all hosts have the same speed Ethernet. Fifty concurrent uploads is acceptable in most cases. However, if the server has more bandwidth (for example, 10 GbE, and the normal hosts are using 1 GbE), then the count is important to maximize bandwidth. It should be at least the difference in speeds (10x in this case).
- The bandwidth limit (Parcel Distribution Rate Limit) should be your Ethernet speed (in MiB/seconds) divided by approximately 16. You can use a higher limit if you have QoS configured to prevent starving other services, or if you can accept the risk associated with higher bandwidth load.
Configuring a Proxy Server
- Select .
- Click the Network category.
- Configure proxy properties.
- Enter a Reason for change, and then click Save Changes to commit the changes.
Configuring the Host Parcel Directory
- Click Hosts in the top navigation bar.
- Click the Configuration tab.
- Select .
- Configure the value of the Parcel Directory property. The setting of the
parcel_dir
property in the Cloudera Manager agent configuration file overrides this setting. - Enter a Reason for change, and then click Save Changes to commit the changes.
- Restart the Cloudera Manager Agent on all hosts.
Configuring Peer-to-Peer Distribution of Parcels
Cloudera Manager uses a peer-to-peer service to efficiently
distribute parcels to cluster hosts. The service is enabled by default
and is configured to run on port 7191
. You can change
this port number, and you can disable peer-to-peer distribution.
- Open Cloudera Manager and select .
- Change the value of the P2P Parcel Distribution
Port property to the new port number.
Set the value to
0
to disable peer-to-peer distribution of parcels. - Enter a Reason for change, and then click Save Changes to commit the changes.
