Since your jobs are at 0%, it might actually be a problem with your hadoop cluster rather than hive. Couple of things to check would be:
1. Does a simple M/R job complete successfully? 2. Do logs for the jobs say something? Are the jobs in running state or pending state? 3. It is possible that job submitted from hive is unable to find the zookeeper quorum. To do that, you need to set "hbase.zookeeper.quorum" property in your hive-site.xml to point to your zookeeper quorum. Hope this helps.
