Big Data
Audience level:


Misconfigurations and bugs break the most Hadoop clusters. Fixing misconfigurations is up to you. Attend this session and leave with the know-how to get your configuration right the first time.


In some support contexts, a handful of common issues account for a large fraction of issues. That is not the case for Hadoop, where even the most common specific issues account for no more than 2% of support cases. Hadoop errors show up far from where you configured, making it hard to know what log files to analyze. In this session, we'll talk about how to avoid making the most common memory, thread, and disk mismanagement mistakes.
