Resolution: Won't Fix
subsumed by HIVE-17915
> OrcSplit.canUseLlapIo() disables LLAP IO for non-vectorized acid reads
> ----------------------------------------------------------------------

> Key: HIVE-17944
> URL: https://issues.apache.org/jira/browse/HIVE-17944
> Project: Hive
> Issue Type: Sub-task
> Components: llap, Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
>
> As of HIVE-17458, the logic for Acid reads is enable LLAP IO for vectorized
> read if VectorizedOrcAcidRowBatchReader can handle it.
> and disable it for any non-vectorized acid read. This last part is on par
> with HIVE-12631.
> The reason is that LlapRecordReader creates VectorizedOrcAcidRowBatchReader
> for acid + vectorization, but doesn't create any Acid aware reader w/o
> vectorization.
