------------------------------------
Summary: TABLESAMPLE does not ignore _SUCCESS and _logs
Key: HIVE-3374
URL: https://issues.apache.org/jira/browse/HIVE-3374
Project: Hive
Issue Type: Bug
Affects Versions: 0.8.1
Reporter: Fabian Alenius
When running a query on an external bucketed table, TABLESAMPLE does not ignore
_logs and _SUCCESS. This means that if you run the select bucket 1 or 2, the
query will fail.
hive> select count(*) from table TABLESAMPLE(BUCKET 1 OUT OF 100 on username)
where var = value;
Total MapReduce jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:
set hive.exec.reducers.max=<number>
In order to set a constant number of reducers:
set mapred.reduce.tasks=<number>
