Hi User, I want to know the difference of query execution time in hive if I use SSD for HDFS and HDD for HDFS. Thanks, Amit

Query is stuck in middle

Hi User, I am running a join query on 100GB table with 10 GB table. My query got stuck without giving any error like below. 2014-11-26 20:19:53,893 Stage-1 map = 99%, reduce = 10%, Cumulative CPU 29443.21 sec 2014-11-26 20:20:53,920 Stage-1 map = 99%, reduce = 10%, Cumulative CPU 29480.04 sec

How to do single user multiple access in hive

Hi users, I have hive set up at multi node hadoop cluster. I want to run multiple queries on top of a table from different machines. So please help how to achieve multiple access on hive to run multiple queries simultaneously. Thanks Amit

Re: How to do single user multiple access in hive

(client) installed on the 'different' machines helps you achieve your goal at the minimalist end. If you use any other program like oozie (to submit your queries) etc. then you can fire queries through the respective interfaces safely enough. regards Devopam On Fri, Nov 7, 2014 at 7:29 PM, Amit
