@deniskuzZ , Thank you for your advice. I tried to reproduce the issue using `TestTezTPCDS30TBPerfCliDriver`, but I couldn't observe any query plan changes so far. I followed these steps to reproduce the issue: 1. Set `hive.metastore.aggregate.stats.cache.enabled` to `true` in `data/conf/perf/tpcds30tb/tez/hive-site.xml`. (Since AggregateStatsCache is a MetaStore feature, we could not enable it using qfile.) 2. Run query5 alone and check query plan. 3. Run queries 64-99, followed by queries 1-5 and then check query plan. According to our records, the plan of query5 differs between step 2 and step 3. However, TestTezTPCDS30TBPerfCliDriver generated the same plan. At the moment, I’m tied up with other tasks, so I won’t be able to dedicate time to this issue in the near future. Additionally, it seems that I need more time to understand our records as this issue is quite old. However, I’ll prioritize this issue at the top of my Hive TODO list and will share any updates as soon as I discover new information. -- This is an automated message from the Apache Git Service.
