> Document 'usehcatalog' parameter on WebHCat calls
> -------------------------------------------------
>
> Key: HIVE-5627
> URL: https://issues.apache.org/jira/browse/HIVE-5627
> Project: Hive
> Issue Type: Sub-task
> Components: Documentation, WebHCat
> Affects Versions: 0.12.0
> Reporter: Eugene Koifman
> Assignee: Lefty Leverenz
> Fix For: 0.13.0
>
>
> The following REST calls in WebHCat:
> 1. mapreduce/jar
> 2. pig
> now support an additional parameter 'usehcatalog'. This is a mechanism for
> the caller to tell WebHCat that the submitted job uses HCat, and thus needs
> to access the metastore, which requires additional steps for WebHCat to
> perform in a secure cluster.
> The JavaDoc on corresponding methods in
> org.apache.hive.hcatalog.templeton.Server describe this parameter.
> Additionally, if templeton.hive.archive, templeton.hive.home and
> templeton.hcat.home are defined in webhcat-site.xml (documented in
> webhcat-default.xml) then WebHCat will ship the Hive tar to the target node
> where the job actually runs. This means that Hive doesn't need to be
> installed on every node in the Hadoop cluster. (This part was added in
> HIVE-5547). This is independent of security, but improves manageability.
> This should be added to the sections in
> https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference that
> correspond to these methods.
