# Apache Hadoop

8 Hacker News commenters recommended Apache Hadoop and 17 criticized it, November 2025 to November 2026. It was recommended in 3 of 13 months.

**Verdict:** Recommended as a known quantity that really works for large-scale work; critics say it is overkill for smaller scale, with a large upfront cost.

## Why people recommend it

- Suited to large-scale workloads (3 comments): "Spark and Hadoop have their place, maybe not in rinky dink startup land" ([source](https://news.ycombinator.com/item?id=46667042)) "Spark and Hadoop have their place" ([source](https://news.ycombinator.com/item?id=46667862)) "Hadoop ought be used for hot data" ([source](https://news.ycombinator.com/item?id=46741880))
- Reliable, well-known in practice (2 comments): "MR and Hadoop etc. would take care of recovering from operational failures like disk or network outages" ([source](https://news.ycombinator.com/item?id=45837834)) "Hadoop is a known quantity and really works." ([source](https://news.ycombinator.com/item?id=46675894))

## What people warn about

- Overkill for small-scale needs (3 comments): "you're definitely paying a large upfront cost for scalability you very much might not need" ([source](https://news.ycombinator.com/item?id=46672804)) "I did not have the heart or courage to tell them during the demo that this was overkill" ([source](https://news.ycombinator.com/item?id=49662468)) "that has trade-offs that typically aren't worth it if you don't need that scale" ([source](https://news.ycombinator.com/item?id=46667156))
- Dated, hard-to-use MapReduce design (3 comments): "Back when Hadoop came along you built operators and these operators communicated through disk" ([source](https://news.ycombinator.com/item?id=47749385)) "Hadoop is still a Map/Reduce clone, thus destined to fail at useability." ([source](https://news.ycombinator.com/item?id=46675598)) "the Hadoop era Java stuff" ([source](https://news.ycombinator.com/item?id=46673432))
- Frustrating, poorly supported in practice (3 comments): "you will get Hadoop levels of non-application support needed" ([source](https://news.ycombinator.com/item?id=49021404)) "that was just an exercise in frustration" ([source](https://news.ycombinator.com/item?id=47288014)) "Its the worst of all possible worlds."
