                 URL: https://issues.apache.org/jira/browse/HUDI-1174
             Project: Apache Hudi
          Issue Type: Sub-task
          Components: bootstrap
            Reporter: Udit Mehrotra
            Assignee: Udit Mehrotra
             Fix For: 0.6.0


Hudi changes for bootstrapped tables integration with Presto.
 * Annotation *UseRecordReaderFromInputFormat* is required on *HoodieParquetInputFormat* as well, because the reading for bootstrapped tables needs to happen through record reader to be able to perform the merge. On presto side, this annotation is already handled.
 * We need to internally maintain *VIRTUAL_COLUMN_NAMES* because presto's internal hive version *hive-apache-1.2.2* has *VirutalColumn* as a *class*, versus the one we depend on in hudi which is an *enum*. This results in following error in presto:
