Eugene Koifman created HIVE-17915: ------------------------------------- Summary: Enable VectorizedOrcAcidRowBatchReader to be used with LLAP IO elevator over original acid files Key: HIVE-17915 URL: https://issues.apache.org/jira/browse/HIVE-17915 Project: Hive Issue Type: Sub-task Components: Transactions Affects Versions: 3.0.0 Reporter: Eugene Koifman Priority: Minor
Reading "original" acid files requires using _org.apache.hadoop.hive.ql.io.orc.RecordReader.getRowNumber()_ in __VectorizedOrcAcidRowBatchReader_ This API is not available on the reader that _LlapRecordReader_ provides so _VectorizedOrcAcidRowBatchReader.canUseLlapForAcid()_ is used to disable LLAP IO in some corner cases. It would be better if getRowNumber() was available for performance as well as simpler logic in the code. This needs HIVE-17458 to be committed to make sense. cc [~sershe], [~teddy.choi] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
