Apache: Big Data 2016

Recent developments within the tracing community have brought projects like Apache HTrace (Incubating) into the Apache Incubator opening up the possibility of utilizing tracing logic to better understand distributed applications, systems and systems-of-systems. As many will know, tracing involves a specialized use of logging to record information about a program’s execution. Although many use cases involve the use of tracing within distributed systems such as Hadoop and databases, few tracing experiments belong within the field of large scale, distributed Web search. This presentation will combine comprehensive tracing mechanisms in Apache HTrace (Incubating) with the scalable, flexible crawling architecture presented by Apache Nutch. Key takeaways from this presentation are development and implementation, tracing guidance for your web search stack and future work in this area.
