Creating a Local Parcel Repository
If the Cloudera Manager server does not have Internet access, you can access the Cloudera parcels directories (at http://archive.cloudera.com/cdh4/parcels/ or http://archive.cloudera.com/impala/parcels/) from another location, and then drop the .parcel file into your local parcel-repo directory.
You will also need to create a .sha file from the information found in the manifest.json file in the parcels directory for the parcel version you want to use.
To make a parcel available for distribution on your cluster:
- Verify the location of the local parcel repository on your Cloudera Manager server: Go to the Administration page, Properties tab, Parcels category. You can change the local repository path in the Local Parcel Repository Path property. By default it is /opt/cloudera/parcel-repo.
- Go to Cloudera's parcel repository at http://archive.cloudera.com/cdh4/parcels/ or http://archive.cloudera.com/impala/parcels/.
- Go to the directory for the software version you want to make available to your cluster.
- Copy the .parcel
file for your operating system: (el5 or
el6 for Red Hat 5 or 6, lucid or precise for Ubuntu and so on) and place it into the local parcel repository on
your Cloudera Manager server.
Note: The local directory must already exists and have its permissions set correctly (they must match the permissions set on /opt/cloudera/parcels).
- Open the manifest.json file in the same directory as the .parcel file you just copied.
- Find the section of the manifest that corresponds to the parcel you downloaded: For
example, if you are running RHEL 6 and copied the parcel file CDH-4.2.0-1.cdh4.2.0.p0.10-el6.parcel, then you
would look for the section:
{ "parcelName": "CDH-4.2.0-1.cdh4.2.0.p0.10-el6.parcel", "components": [ { "name": "flume-ng", "version": "1.3.0-cdh4.2.0", "pkg_version": "1.3.0+86" } ,{ "name": "mr1", "version": "2.0.0-mr1-cdh4.2.0", "pkg_version": "0.20.2+1341" } ,{ "name": "hadoop-hdfs", "version": "2.0.0-cdh4.2.0", "pkg_version": "2.0.0+922" } . . . . <snip> . . . ,{ "name": "whirr", "version": "0.8.0-cdh4.2.0", "pkg_version": "0.8.0+21" } ,{ "name": "zookeeper", "version": "3.4.5-cdh4.2.0", "pkg_version": "3.4.5+14" } ], "hash": "f1a08b5f7aeef6335d577c5f6fad0bca55f0c2d9" },
- Create a text file whose name is <parcel file
name> .sha (e.g. CDH-4.2.0-1.cdh4.2.0.p0.10-el6.parcel.sha) and copy the hash code into it: e.g.
# cat > CDH-4.2.0-1.cdh4.2.0.p0.10-el6.parcel.sha f1a08b5f7aeef6335d577c5f6fad0bca55f0c2d9 ^C
- Place this file into your local parcel repository.
- Once these files are in place, Cloudera Manager will pick up the parcel and it will appear on the Hosts > Parcels page. Note that how quickly this occurs depends on the Parcel Update Frequency setting, set by default to 1 hour. You can change this on the Administration page, Properties tab, Parcels category.
