Hello,
I am using CDH 5.14, on VirtualBox with 10Gb memory 2 nodes cluster.
I wanted to test the hive functionality so i set the nodemanager memory to 2.6G.
Created hive table with 8000 rows in text format.
when i try to count the rows through hive it did not progress as follows, can you please give some hints:
hive> select count(*) from geo;
Query ID = hdfs_20180416185858_a1bbf6cb-0d82-4682-90ef-0ef49a5d1777
Total 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 mapreduce.job.reduces=<number>
