[jira] [Updated] (HIVE-17854) LlapRecordReader should have
getRowNumber() like org.apache.orc.RecordReader
[ https://issues.apache.org/jira/browse/HIVE-17854?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eugene Koifman updated HIVE-17854:
----------------------------------
Description:
getRowNumber() is required to read data in non-acid tables that were converted to acid.
Currently when VectorizedOrcAcidRowBatchReader is used from LlapRecordReader this functionality is not available making it impossible to vectorize reads/updates of non-aicd-to-acid tables with LLAP (until major compaction) in the presence of any deletes.
