Eugene Koifman created HIVE-17944: ------------------------------------- Summary: 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. cc [~sershe], [~teddy.choi] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
