Subject [jira] [Commented] (HIVE-16730) Vectorization: Schema Evolution for Text Vectorization / Complex Types
Date Thu, 01 Jun 2017 04:51:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16032440#comment-16032440

Teddy Choi commented on HIVE-16730:
-----------------------------------

This patch makes HIVE-16589 able to evolve schema in STRUCT. However, column c5 of the last
record in schema_evol_text_vec_part_all_complex.q.out becomes null, not 1255178165 after applying
HIVE-16730 on HIVE-16589. I think that it's related with LazySimpleDeserializeRead or LazySimpleSerializeWrite.

fail.
