How MapReduce Has Become YARN In Hadoop?

MapReduce has been changed completely in last few months and now it has become YARN (Yet Another Resource Navigator). So what should be used for your business either MapReduce or YARN? Which is better platform to manage Hadoop application software?

Hadoop Application Software

Resource Manager is one of the very important components available in YARN assures profits for your business. Further Resource Manager is divided into two parts – Scheduler and Application Manager.

When applications are in running state, the job of scheduler is to allocate resources in proper way. The just schedules resources, it does not monitors or tracks the Hadoop Application status. Also it does not make sure that tasks will be restarted once they are failed. The reason for failure of app may be hardware limitation, software problems or other resource allocation issues.

The scheduler generally completes its task based on application requirements and ignores other components usually that include CUP, memory, network, disk usage etc.  Next comes to Application Manager that manages task like monitoring progress, reporting status etc. Further resource manager is also clubbed up with high availability feature to make it more suitable for the job.

Resource Manager RM restart

Resource Manager Restart is a feature that enhances functionalities of resource manager to keep them active all the time. It is further divided into two phases – P1 and P2. P1 or phase 1 restores previous state where resource manager stopped working. It synchronizes overall process of Hadoop application or Hadoop software.

Phase 2 or P2 reconstructs running state of resource manager. It means application will not lose its productivity when it will be restarted.

  • Phase 1 Restart

The overall concept is that RM restart will resume metadata of Hadoop application and also stores final state of an application. Besides the final state, it also stores application credential like security key, code etc. It picks up metadata and resubmit the application. Simple resource manager cannot resubmit the application.

  • Phase 2 Restart

In Phase 2 also, RM restart will resume metadata of Hadoop application and also stores final state of an application. Besides the final state, it also stores application credential like security key, code etc. It picks up metadata and resubmit the application. Simple resource manager cannot resubmit the application. After this, it has the capability of preserving the previous state so application work will not lose even if it will be restarted later.

Do The Risks Cover Up The Major Benefits Of Outsourcing CRM Services?

Most businesses are finding CRM outsourcing as essential tool to keep their management and sales team’s operations smooth. About 40% of CRM based applications are hosted over cloud and still counting. But this is not what you can expect with outsourcing CRM and integration services operations, such as sales programs or customer care. Companies do hesitate to outsource these operations- of course, for good reason.

Outsorucing CRM

Outsourcing has its own benefits- it is cheaper, scalable, and faster to implement. What has changed is companies now have to deal with people and not with software. Managing CRM operations in-house is always good and better than outsourcing – but only for companies that can invest their huge time and resources in order to get great quality user experience without affecting other critical business aspects. But if you can’t afford this luxury, then you have no option left except outsourcing CRM services to third party vendor.

Outsourcing best fits here-

  • Operations- There is only one thing that third party vendor bring and that’s the expertise. It is important for vendors to deliver quality service to customers. Outsourcers offering complete and continuous training program to their staff and making investment in latest technologies to integrate and support multichannel interaction, such as social media, email, and telephone.
  • Growth – There is always a scope of growth when you hire third party vendor or outsource CRM services like customer care.
  • Cost- You should not be mistaken by assuming that your outsourcing partner will be cheaper than managing internal operations, there are chances when you will end up spending less while outsourcing. Moreover, you don’t need to invest in high-end infrastructure or train staff employees.

And the problem is-

  • Data- Companies are facing difficult time in maintaining data. Over the time, data records get larger and maintaining the integrity of such records becomes difficult.
  • Control- In case you have outsourced customer care from third party vendor, you will lose your brand control.
  • Relationships- CRM is about managing customer relationship and in case your vendor fails to maintain customer relationship and clients are unsatisfied, then you will end up losing your clientele.

May be due to such risks, many companies are skipping looking at the benefits of CRM outsourcing. But, still there are businesses daring to avail such services to get the best results and growth.
