wrapping up my 8 year hortonworks – cloudera adventure (best job ever)
what an amazing eight years at hortonworks/cloudera — the technology, the focus, the use cases, the domains, the FUN and most importantly, the PEOPLE, made this the best job of my entire career and make it super hard to say goodbye to this role
updated streaming supervision features scorecard (added flink)
added apache flink to the comparison grid of kafka streams, spark streaming, and storm focused on the features they offer the operations side of the devops formula — it measures up well
batch as a “special case” of flink streaming (yes, now we’re mv’ing streaming back to batch)
the third part of a loosely coupled trilogy on flink batch and streaming that take us full-circle with the collapse of the DataSet API into the DataStream API — i’m not sure Run-D.M.C. could make this less tricky
mv’ing batch flink to streaming (easy breezy)
building on a prior post, this tutorial ports a simple flink batch program to become a streaming solution – put lakeside on the turntable and let’s finish up the fantastic voyage
hello world with flink (from scratch)
come along and ride on a fantastic voyage where we will setup an apache flink environment, code up a very simple job, and execute it & verify our results — we’ll just slide, glide, slippity-side
big data api’s look a lot alike (code comparison with flink, kafka, spark, trident and pig)
exploring the similarity of the APIs from flink, kafka streams, spark (RDDs & DFs), storm’s trident and yes, even good old pig by implementing the canonical word count solution with each framework
functional programming and big data (what a pair)
a high-level overview of how functional programming with immutable datasets is a great partner with big data processing frameworks — code examples with spark rdds using scala
building a spark sql udf with scala (using multiple arguments)
a short & sweet code-focused tutorial declaring a scala function as a spark sql udf that can be leveraged via the api approach or in a formal sql statement
joining spark dataframes with identical column names (not just in the join condition)
a quick walkthru of spark sql dataframe code showing joining scenarios when both tables have columns with the same name; this includes when they are used in the join condition as well as when they are not
