I grepped an export of the Hive wiki for 'sample(' and 'sample (' but only
found tablesample in these three docs:
-
https://cwiki.apache.org/confluence/display/Hive/Tutorial#Tutorial-Sampling
-
https://cwiki.
If it should be sampled using subquery would be inevitable, something like,
select x from (select distinct key as x from src)a where rand() > 0.9 limit
10;
