Hi,

I am running select count(*) on a hive table created on hive schema on a freshly installed cdh 5.3 version for POC purpose.

But the query hangs after executing upto kill command .

Any help in resolving this will be appreciated

hive> select count(*) from id;               
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>
Starting Job = job_1437996970870_0002, Tracking URL = http://01HW******************com:8088/proxy/application_1437996970870_0002/
Kill Command = /usr/lib/hadoop/bin/hadoop job  -kill job_1437996970870_0002

Running on debugger the process is stuck at
