Hello All, Has anyone been successful at running hive 0.11 with Cloudera CDH 4.3?
I've been able to get hive to connect to my metadb (which is in Postgres). Verified by doing a show tables.. I can run explain and describes on tables, but when I try to run anything that fires off an M/R job, I get the following error: hive>select count(*) from tableA; 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> Starting Job = job_201307112247_13816, Tracking URL = http://master:50030/jobdetails.jsp?jobid=job_201307112247_13816 Kill Command = /usr/lib/hadoop/bin/hadoop job -kill job_201307112247_13816 Hadoop job information for Stage-1: number of mappers: 1; number of reducers: 1 2013-07-12 02:11:42,829 Stage-1 map = 0%, reduce = 0% 2013-07-12 02:12:08,173 Stage-1 map = 100%, reduce = 100% Ended Job = job_201307112247_13816 with errors Error during job, obtaining debugging information...

I've done a bunch of googling around and have found a bunch of other folks that have have had the same issue, but no solid answers.. Thanks in advance for any help.. JC
