Soundararajan Velu commented on HIVE-11269:
-------------------------------------------
during runtime I get the below exception when I run the same query on MR, on
Tez I get it on the console itself as described in the previous commment,
Launching Job 10 out of 11
Number of reduce tasks not specified. Estimated from input data size: 300
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 mapreduce.job.reduces=<number>
