How to install Hcatalog/WebHcat in CDH4.3

I installed CDH enterprise version  CDH-4.3.0-1.cdh4.3.0.p0.22 through cloudera manager 4.6, now I don't know how to install HCatalog/WebHcat on it.

From cloudera manager UI there is no new Parcels for HCatalog.

Then I tried to install it from command line: yum install webhcat-server, but I noticed the yum doesn't recognized the current installed CDH version on my cluster, it will install a full distribution of version 0.5.0+9-1.cdh4.3.0.p0.12.el6. I suspect this is a problem of compatible of Parcels and yum, appreciate somebody can point me how to make Hcatalog available.

 

Thx.

Cloudera Manager CM 4.6 does support WebHCat.

Re: How to install Hcatalog/WebHcat in CDH4.3

While it's possible to install hcatalog and related packages via yum and using the rest of the CDH stack from the parcel, I would recommend not mixing and matching packages and parcels. Hcatalog is doesn't come as a separate parcel, it's present in the CDH parcel.

 

As far as WebHcat goes, it's a "role" of the Hive service. So, you should be able to go to Hive service and add the WebHcat role. Please let me know if you aren't able to find it (or if it's hard to find). Feedback welcome!
