[jira] [Created] (HIVE-14794) HCatalog support to pre-fetch for Avro tables that use avro.schema.url.

Mithun Radhakrishnan created HIVE-14794:
-------------------------------------------

             Summary: HCatalog support to pre-fetch for Avro tables that use avro.schema.url.
                 Key: HIVE-14794
                 URL: https://issues.apache.org/jira/browse/HIVE-14794
             Project: Hive
          Issue Type: Bug
          Components: HCatalog
    Affects Versions: 2.1.0, 1.2.1
            Reporter: Mithun Radhakrishnan
            Assignee: Mithun Radhakrishnan


HIVE-14792 introduces support to modify and add properties to table-parameters during query-planning. It prefetches remote Avro-schema information and stores it in TBLPROPERTIES, under {{avro.schema.literal}}.

We'll need similar support in {{HCatLoader}} to prevent excessive reads of schema-files in Pig queries.
