Eugene Koifman updated HIVE-4749:
---------------------------------
Description:
webhcat-default.xml (webhcat-stie.xml) has templeton.hive.properties which
specifies values of some properties to pass to hive, in particular
hive.metastore.uris. This is then passes as a start up parameter to Hive when
WebHCat launches Hive to execute a query. (The design is that for job
submission WebHCat expects a Hive metastore to be running somewhere.)
On the other hand, when a DDL operation is executed, WebHCat ignores
webhcat-default.xml and expects hive-site.xml to contain hive.mestastore.uris,
etc.
This is very confusing (unless you happen to know this).
There should be a single source of truth.
Since we always expect Hive to be installed on the machine running WebHCat (to
execute DDL command), we should probably get rid of templeton.hive.properties
in webhcat-default/site.xml and get this from hive-site.xml.
