Lefty Leverenz commented on HIVE-5627:
--------------------------------------
Missed the update removing "hive" from the list, sorry.
The rest of my comment just points out inconsistencies to fix in the javadocs
(internal variable names should not appear there) and omissions in the
Map<String, Object> code that might or might not need fixing. Plus a question
of whether "enablelog" needs to be documented, but that's just something I
noticed while researching "usehcatalog" so it doesn't belong in this ticket.
Considering how many inconsistencies I found in these three calls, the other
calls should probably be checked for accuracy too.
Does the information about shipping the Hive tar to the target node only apply
to mapreduce/jar and pig when "usehcatalog" is true, or is it more general
information?

> 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.
