Eugene Koifman updated HIVE-5627:
---------------------------------
Description:
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.
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 should be added to the sections in
https://cwiki.apache.org/confluence/display/Hive/WebHCat+Reference that
correspond to these methods.
