Eugene Koifman commented on HIVE-5627:
--------------------------------------
[~le...@hortonworks.com] I'm not sure if I understand your comment. The
purpose of this ticket is to document that mapreduce/jar and pig REST calls now
have additional 'usehcatalog' parameter as well as webhcat-default.xml
properties that are used in conjunction with 'usehcatalog'. "hive" doesn't
support this parameter. What the internal variable name is in Java is not
relevant to end users. The names in FormParam("usehcatalog") is what the REST
call expects in the query string.
> 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.
