Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Participants explore the Sentry architecture applied to Hadoop clusters, configure SDKs to capture errors in Spark and MapReduce jobs, perform practical exercises on real Data Lakes, analyze concrete business cases, and produce an initial deliverable for distributed monitoring configuration.
This day deepens Sentry integration into Data Lake architectures, optimizes error capture performance on massive volumes, uses distributed tracing tools, practices scalability scenarios with Hadoop, and generates a deliverable for a customized real-time monitoring dashboard.
Learners design advanced alerting rules for Hadoop pipelines, automate incident response workflows, integrate Sentry with third-party Big Data tools, perform exercises on professional cases, and deliver a complete certifying automation strategy.
The session focuses on in-depth analysis of errors collected by Sentry in Hadoop environments, leverages metrics to optimize Data Lakes, practices customized reporting, studies concrete business cases, and produces a Big Data performance audit deliverable.
Participants deploy Sentry in production on Big Data infrastructures, secure data flows, implement continuous maintenance of Hadoop clusters, validate skills through a final project, and obtain a certifying deliverable for the enterprise.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
