Vantaggi
Great open source oriented company. Full support given for open source contributions and get Apache badges committer and PMC. At the same time we need to work on proprietary software which also works like an in-house open source community. Linux, MBP desktops, big monitors, nice offices. Very nice workplace.
Svantaggi
Apache Hadoop and related open source components are far from being perfect. Big legacy codebases, low coding quality, awful testing coverage and quality, spaghetti bloatware everywhere. Given all this you have to work on though, complicated distributed problems and deliver reliable solutions. Not easy. Cloudera gets money from support. Support is not easy, because of the above. Escalations are raised every so often, because customers are running into bugs all over the place. In house developments are also way overcomplicated and not maintained properly. Overall: good money for a challenging work.
