Hello Andrew Sherman, Tamas Mate, Daniel Becker, lipeng...@sensorsdata.cn,
Gergely Fürnstáhl, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#5).
Change subject: IMPALA-11582: Implement table sampling for Iceberg tables

IMPALA-11582: Implement table sampling for Iceberg tables
This patch adds table sampling functionalities for Iceberg tables.
>From now it's possible to execute SELECT and COMPUTE STATS statements
with table sampling.
Predicates in the WHERE clause affect the results of table sampling
similarly to how legacy tables work (sampling is applied after static
partition and file pruning).
Sampling is repeatable via the REPEATABLE clause.
Testing
* planner tests
* e2e tests for V1 and V2 tables
