Hi, my MR jobs run very slow on hadoop, some block in reduce tasks -input data is small, number of splits is 2 -memory is available ('free -m' shows a usage under 4GB per node), each node has 32GB -yarnchild(s) are consuming 100% CPU (tests with "top") and I don't find ways to improve performance best -- This message was sent by Atlassian JIRA (v6.2#6252)
