yahoodevelopers: Kuhu Shukla (bottom center) and team at the 2017 DataWorks Summit By Kuhu Shukla This post first appeared here on the Apache Software Foundation blog as part of ASF's "Success at Apache" monthly blog series. As I sit at my desk on a rather frosty morning with my coffee, looking up new JIRAs from the previous day in the Apache Tez project, I feel rather pleased. The latest community release vote is complete, the bug fixes that we so badly needed are in and the new release that we tested out internally on our many thousand strong cluster is looking good. Today I am looking at a new stack trace from a different Apache project process and it is hard to miss how much of the exceptional code I get to look at every day comes from people all around the globe. A contributor leaves a JIRA comment before he goes on to pick up his kid from soccer practice while someone else wakes up to find that her effort on a bug fix for the past two months has finally come to fruition through a binding +1. Yahoo - which joined AOL, HuffPost, Tumblr, Engadget, and many more brands to form the Verizon subsidiary Oath last year - has been at the frontier of open source adoption and contribution since before I was in high school. So while I have no historical trajectories to share, I do have a story on how I found myself in an epic journey of migrating all of Yahoo jobs from Apache MapReduce to Apache Tez, a then-new DAG based execution engine. Oath grid infrastructure is through and through driven by Apache technologies be it storage through HDFS, resource management through YARN, job execution frameworks with Tez and user interface engines such as Hive, Hue, Pig, Sqoop, Spark, Storm. Our grid solution is specifically tailored to Oath's business-critical data pipeline needs using the polymorphic technologies hosted, developed and maintained by the Apache community. On the third day of my job at Yahoo in 2015, I received a YouTube link on An Introduction to Apache Tez. I watched
