This document summarizes how logging was improved for Apache Spark jobs on Amazon EMR. It discusses: 1) Previously, logs had to be accessed directly on servers or downloaded, which was difficult. A solution was developed using bootstrap actions to install Filebeat and Metricbeat, shipping logs to Redis then to Elasticsearch for analysis in Kibana. 2) Main obstacles included resistance to change from data engineers. 3) Future additions could replace Redis with Kafka and collect logs from other services like Druid and Kafka.
