-----------------------------------
Summary: Hudi changes for bootstrapped tables integration with
Presto
Key: HUDI-1174
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:
