As the experts in distributed computing performance, Pepperdata is keenly aware of the challenges all organizations face when running Hadoop in production. Getting your cluster to run optimally is no easy feat, which is why it’s imperative to understand the underlying cause of performance issues so that they can be corrected, or better yet, averted altogether.

Feeling fluxed?

If you’re wondering whether or not your organization is experiencing a bad case of what we like to call “Cluster Flux”, ask yourself these questions:

  • Do your Hadoop jobs run too slowly or freeze periodically?
  • Do you find yourself unsuccessfully trying to manually tune your multi-workload, multi-tenant environment?
  • Have you tried debugging resource contention issues only to find you don’t have sufficient visibility to identify the root cause?
  • Does your cluster consistently show idle capacity, but you find that you can’t start new jobs?

If you answered yes to one or more of these questions, then it’s time to seek help from the experts. Luckily, at Pepperdata we’ve made performance of distributed computing our business, and after running in production on over 100 clusters worldwide, we know how to not only diagnose and solve these symptoms, but in most cases avert them altogether. Pain free Hadoop? Who knew! (well, we kinda did . . .)
The data we’ve collected from hundreds of clusters worldwide has helped us uncover the most common and insidious Hadoop performance challenges faced by companies big and small. Some of the most prevalent issues plaguing current Hadoop users include lack of expertise, too much time spent troubleshooting, cluster slowdowns from resource contention, and lack of visibility. Sound familiar? These are all common symptoms of Cluster Flux and should be treated immediately.

We decided to use one of our favorite childhood games to visualize what ails a Hadoop cluster, and provide a bit more about the cause of (and remedy for) the eight most common symptoms of Cluster Flux.  Before you start worrying too much about the ill effects these problems can have on your Hadoop environment – know that there is a fix! At Pepperdata, we’re even offering a free cluster health check to organizations with Hadoop clusters of 100 nodes or more, that want to assess the health of their cluster.
