Most companies today rely on Hadoop for their big data processing needs. However, such a sophisticated platform can still present problems and challenges that DevOps teams grapple with almost every day.
Hadoop challenges can usually be summed up into three main issues. Continue reading to find out what these are, and see how Pepperdata takes care of these problems.
Challenge #1: The Difficulty in Finding Root Cause of Problems
Picture this: a production job is running late, and users are complaining. And so, you check the monitoring system, asking yourself, “Is a node down? Is a cluster busy?”
But you can’t tell what’s happening. So you ask around for anyone who might have done anything differently to solve your Hadoop problem. No one has anything to offer because, most probably, everyone else is as clueless as you are. You can’t even replicate the problem, much less find what started it. And so you decide to let Hadoop operations run while you watch and wait, hoping and praying that the next time the problem reappears, you’re there to witness it.
Unsurprisingly, the Hadoop problem resurfaces. Hurrah! Now you can jump in to do some node debugging. Only… you still don’t see where the problem is coming from. You’re not even sure which resources to tweak. Still, you make adjustments here and there, then you sit back and play the waiting game again. Eventually, you decide you’ll need to buy extra hardware just to buy yourself some peace. But really, in the back of your mind, there’s a nagging worry that this same issue with Hadoop will happen again.
Now did that feel like a day in your life? It probably did.
But with Pepperdata solutions, you get visibility from all corners. Every five seconds, Pep Agents collect more than 350 real-time operational metrics from applications and infrastructure resources, including CPU, RAM, disk I/O, and network usage metrics on every job, task, user, host, workflow, and queue.
The user doesn’t need to sift through this data to look for Hadoop problems; Pepperdata swiftly derives insights from the metrics to solve the problem at hand. This gives you full 360-degree visibility into application performance within the context of your big data infrastructure, whether on-premises or in cloud/hybrid environments.
Challenge #2: Inefficient Cluster Utilization
Let’s face it: production clusters struggle to fully utilize their full capacity given the constraints of the YARN scheduler. No matter how tuned your Hadoop is, these clusters are sized for peak SLA, and with Hadoop’s allocations being predefined and static, a lot of computing capacity gets wasted.
And what about ad-hoc jobs? They sit in their own production cluster queue, until someone runs a rogue job, using more resources than a given queue can handle, and causing other jobs to run late.
The more jobs and workloads you have, the more clusters you set up to isolate them. More clusters = more wasted capacity and the potential for Hadoop problems.
Not with Pepperdata Capacity Optimizer. Capacity Optimizer reclaims wasted capacity by leveraging patented, machine learning based automation.This allows you to use the true capacity of your hardware.
Challenge #3: The business impact of Hadoop inefficiencies
Hadoop problems can create major consequences for the business – especially on the financial side.
- A key customer-facing web feature not performing can lose the company up to $10,000/hour.
- Unavailable real-time ad impression data can lose you up to $5,000/minute.
- For every half-hour that problems remain unfixed, up to 150 customers leave your app.
- Operators can waste thousands of dollars worth of productivity per day backtracking and tracing the root cause of Hadoop problems.
- Sluggish or offline external-facing reporting systems can bring your customer satisfaction down and drive churn.
- Consequently, late and/or unavailable reports can make you lose $5,000 worth of productivity per hour, and this cascades throughout the organization.
Pepperdata can help you with curbing these loses and more. Proactive application monitoring with Pepperdata Platform Spotlight helps raise the flag on symptoms before they become problems, from finding sluggish queries to identifying high volume requests that should be optimized. Companies can save annual costs of up to 70%, assuming at least a 70% reduction in mean-time-to-repair (MTTR).
This all comes to life in a recent case study of ours. A leading Fortune 100 multinational investment bank and financial services corporation, headquartered in the U.S., needed an intelligent solution to address the problem of runaway data center growth and constantly increasing spend on compute infrastructure.
With the help of Capacity Optimizer, they reduced their infrastructure spend by nearly 30% by recapturing wasted resources, maximizing the capacity of their existing infrastructure, and ensuring that workloads performed optimally. For this customer, the approximate 30% improvement in server utilization and capacity is equivalent to 100s of nodes, significantly reducing the number of additional servers needed to support continued growth.
Whatever Hadoop issues or challenges you may have, Pepperdata can easily integrate into your system and solve them. It only takes about 20 minutes to set up. You can even use your existing Hadoop, with its existing schedulers and with no change to job submission. Request demo here.
