-------------------------------------------------

             Summary: set the value of metastore.storage.schema.reader.impl
 to org.apache.hadoop.hive.metastore.SerDeStorageSchemaReader as default
                 Key: HIVE-26952
                 URL: https://issues.apache.org/jira/browse/HIVE-26952
             Project: Hive
          Issue Type: Improvement
          Components: Standalone Metastore
            Reporter: Taraka Rama Rao Lethavadla
            Assignee: Taraka Rama Rao Lethavadla


With the default value of

 
{code:java}
DefaultStorageSchemaReader.class.getName(){code}
 

in the Metastore Config, *metastore.storage.schema.reader.impl*

below exception is thrown when trying to read Avro schema
{noformat}
Caused by: org.apache.hive.service.cli.HiveSQLException: MetaException (message:java.lang.UnsupportedOperationException: Storage schema reading not supported)

setting the above config with *org.apache.hadoop.hive.metastore.SerDeStorageSchemaReader* resolves issue

Proposing to make this value as default in code base, so that in upcoming versions we don't have to set this value manually
