How do I get the full parcel version running currently on a CDH cluster?

[#1]

I using version 10 of the python CM API and am having issues getting the reference to the correct parcel in our cluster.  Currently, we have 4 or 5 parcels located in the cluster and I am not able to select the correct one.  I see the ApiCluster method :

get_parcel(self, product, version)

, but I don't know where to find the full parcel version to pass into this method using other API calls.  A version string = "5.4.0" is not specific enough to find the correct parcel.

Thanks,

Tyler

Hi Tyler,

Here are various ways to identify the full parcel version - 

Identifying by the parcel filename:

http://archive.cloudera.com/cdh5/parcels/latest/CDH-5.3.5-1.cdh5.3.5.p0.4-el6.parcel

CDH is the product

5.3.5-1.cdh5.3.5.p0.4 is the version

el6 is the distribution that the parcel is intended to be deployed on

In the manifest.json eg: http://archive.cloudera.com/cdh5/parcels/latest/manifest.json

...

"parcelName": "CDH-5.3.5-1.cdh5.3.5.p0.4-el6.parcel",

...

and in Cloudera Manager Web UI / http://CM-SERVER:7180/cmf/parcel/status the highlighted in yellow is the full version.

example CM API usage, using python regex:

Hope this helps,

Thanks Michalis.

I was able to get the current activated parcel by searching for the product "CDH" and selecting the one who's stage ="ACTIVATED" using the CM API.
