I am trying to find a tool, which would show me an overview of my Hadoop ecosystem - state, health, running tasks, etc. I tried to Google, but did not find any. Is there some nice useful tool?
Tell me more

Running tasks, mapred node state/health: http://example.com:50030/jobtracker.jsp HDFS health and node state: http://example.com:50070/dfshealth.jsp Replace example.com with the IP or hostname of your job tracker / name node. If those ports aren't correct check your mapred-site.xml and hdfs-site.xml for the defined port. |

Cloudera offers a proprietary tool which does what you describe and more called Cloudera Manager. It isn't F/OSS, but they do have a free edition that lets you run on some limited number of nodes. It's meant as a full lifecycle product, so it might be a bit overkill for what you need. Full disclosure: I've never used it myself. We considered it at my company, but ended up not using it. |
