A Benchmark Test on Presto, Spark Sql and Hive on Tez
Presto、Spark SQLとHive on Tezの性能に関して、数万件から数十億件までのデータ上に、常用クエリパターンの実行スピードなどを検証してみた。 We conducted a benchmark test on mainstream big data sql engines including Presto, Spark SQL, Hive on Tez. We focused on the performance over medium data (from tens of GB to 1 TB) which is the major case used in most services. Read less
Google BigQuery Benchmark — DoIT International :: Helping businesses adopt, manage and enhance cloud solutions from Google and Zendesk
By Vadim Solovey, Google Developer Expert.Recently, I came across an interesting benchmark of BigData systems based on "A Comparison of Approaches to Large-Scale Data Analysis" by Pavlo et al. (SIGMOD 2009). Based on the benchmark methodology, the APMLab guys from Berkeley University developed an open-source software that allows anyone to run this benchmark using public cloud (AWS in this case).Th
Hive on Tez を CDH で動かす - Qiita
Tezとは まずはTezの説明です。 TezはYARN上で動作するバッチ処理用のフレームワークで、Hortonworksが主導して開発しています。 Tezに近い位置付けのものには、リアルタイム処理用のSliderがあります。 HortonworksはSliderの上でStormを動かすことを計画しています。 Hive on Tezとは Hive on Tezは、上記のTezの上でHiveを動かすものです。 Hive 0.13からTez対応のパッチが入っていて、動かす準備はできています。 しかし、ClouderaはCDH 5.2でHive 0.13に対応したものの、Tezをパッケージングしませんでした。 そのため、そのままのCDHではHive on Tezが動きません。 Hive on TezをCDHで動かす方法 Tezはライブラリであるため、CDHのHive 0.13と組み合わせれば動作す

War of the Hadoop SQL engines. And the winner is ...? - Sonra
War of the Hadoop SQL engines. And the winner is …? You may have wondered why we were quiet over the last couple of weeks? Well, we locked ourselves into the basement and did some research and a couple of projects and PoCs on Hadoop, Big Data, and distributed processing frameworks in general. We were also looking at Clickstream data and Web Analytics solutions. Over the next couple of weeks we wil

Yahoo Betting on Apache Hive, Tez, and YARN
by The Hadoop Platforms Team Low-latency SQL queries, Business Intelligence (BI), and Data Discovery on Big Data are some of the hottest topics these days in the industry with a range of solutions coming to life lately to address them as either proprietary or open-source implementations on top of Hadoop. Some of the popular ones talked about in the Big Data communities are Hive, Presto, Impala, S

Tezの特性について
とりあえずいまのところの理解をまとめておこうかと思います。 ご参考 http://www.infoq.com/presentations/apache-tez http://qconsf.com/system/files/presentation-slides/Apache-Tez-Accelerating-Hadoop-Query-Processing.pdf まず、先のリンク先の動画の冒頭のところで言及されているように、TezそのものはYARNにおける並列処理エンジンについてMapReduceの代替となること意識しているようです。その意味では、Tezを近年にみられるImpalaなどのリアルタイムクエリ系と同列にHiveのパフォーマンスを向上させるものだけであると見るのはあまり妥当ではなさそうです。 また、資料ではStreamingを将来においてサポートすると言っていて、Tezだけででラ
Hadoop Summit 2014でのTezがらみのセッションまとめ
いまだにテザリングでしかインターネッツに接続できなくて、それでなくても消費税増税と引っ越しシーズンが重なったことによる生活環境のセットアップに難儀しています。こういうのもDockerとかでスクリプト書いておけばどうにかできるようになりませんか？まあ、とにかく、とりあえずウェッブ・ページにはアクセスできるし、チラ見したネタを拾っておきます。 ネタはHadoop Summit 2014の日程からで、萌豚とヤフーが主催というかえらいスポンサーであることもあり、Tezと関連するセッションがあって、それを抜粋したよというライトめなネタです。 セッションは4つほどあるようなので、先のURLからのコピペと感想文をあれしていきます。 Apache Tez - A New Chapter in Hadoop Data Processing Bikas Saha, Hitesh Shah Apache Tez

Apache Tez: Accelerating Hadoop Query Processing
This document discusses Apache Tez, a framework for accelerating Hadoop query processing. Some key points: - Tez is a dataflow framework that expresses computations as directed acyclic graphs (DAGs) of tasks, allowing for optimizations like container reuse and locality-aware scheduling. - It is built on YARN and provides a customizable execution engine as well as APIs for applications like Hive an

Click Here for the previous version of the benchmark Introduction Several analytic frameworks have been announced in the last year. Among them are inexpensive data-warehousing solutions based on traditional Massively Parallel Processor (MPP) architectures (Redshift), systems which impose MPP-like execution engines on top of Hadoop (Impala, HAWQ), and systems which optimize MapReduce to improve per
