             Summary: WebHcat looses column comments and returns 'from deserializer'
                 Key: HIVE-4703
                 URL: https://issues.apache.org/jira/browse/HIVE-4703
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
    Affects Versions: 0.12.0
            Reporter: Eugene Koifman
             Fix For: 0.12.0
         Attachments: webhcatMini.sh

This causes Templeton e2e tests to fail.

start WeHcat server (build/dist/hcatalog/sbin/webhcat_server.sh start)

run commands in the attached webhcatMini.sh.
It creates a table with some comments on columns.

When executing describe (GET) on this table, original comments are lost and are replaced with "from deserializer" string.

Here is the output of these commands:
