Change subject: IMPALA-4854: Fix incremental stats with complex types. ...................................................................... IMPALA-4854: Fix incremental stats with complex types. The bug: Compute incremental stats used to always do a full stats recomputation for tables with complex types. The logic for detecting schema changes (e.g. an added column) did not take into consideration that columns with complex types are ignored in the stats computation, and should therefore not be recognized as a new column that does not yet have stats. Testing: - Added a new regression test - Locally ran test_compute_stats.py and the FE tests Change-Id: I6e0335048d688ee25ff55c6628d0f6f8ecc1dd8a --- M fe/src/main/java/org/apache/impala/analysis/ComputeStatsStmt.java M testdata/workloads/functional-query/queries/QueryTest/compute-stats-incremental.test 2 files changed, 47 insertions(+), 9 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/33/6033/1 -- To view, visit http://gerrit.cloudera.org:8080/6033 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: newchange Gerrit-Change-Id: I6e0335048d688ee25ff55c6628d0f6f8ecc1dd8a Gerrit-PatchSet: 1 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Alex Behm <alex.b...@cloudera.com>
