Hallo zusammen, ich versuche derzeit die Sage New Classic 5.1 (2012) auf einem Linuxserver zu installieren. Im Folgenden die Konstellation: Server: openSUSE 11.3 x64. This is a quick guide on how to install mod. Migrating systems to the public cloud requires many steps, and one of them should be performance monitoring. Here are 5 ways IT pros can make sure their company is.

Benchmarking Apache Hive 1. Enterprise Hadoop. Introduced in 2. 00.

Apache Hive has been the de- facto SQL solution in Hadoop. By 2. 01. 2, SQL had become a key battleground for Hadoop and many vendors started to publish benchmarks showing massive performance advantages their solutions had over Hive. Each of these vendors predicted that Hive would eventually be supplanted by the proprietary solution they were pushing. The concerns about Hive’s performance were real. Hadoop in 2. 01. 2 was a purely batch platform and no work had ever been done within Hive to address low- latency or interactive workloads. The big question remained: was it possible to make Hive fast natively in Hadoop, or did people really need to abandon Hadoop and bolt on a foreign SQL engine strictly to satisfy the one use case of interactive query?

For Hortonworks the choice was obvious. The core of Hortonworks’ philosophy is 1. Hadoop, bolting a solution on the side for one use case creates major operational headaches and would have been a major disservice to our customers. At the same time, Hadoop needed to move beyond purely batch and into interactive and real- time use cases. The introduction of YARN in Hadoop 2 meant interactive query could be developed natively in Hadoop rather than as a bolt- on. The Apache Community at Its Best.

The Stinger Initiative. The 3 major pieces driving performance gain are Apache Tez, the next- generation data processing engine for Hadoop that enables batch and interactive data processing at large scale, Hive’s new Vectorized Query engine, and ORCFile, a columnar format providing high compression and high performance. As we detail in the results section below, 1. SQL analytics. More than 1.

Average speedup of 6. Average speedup of 5. Total time to run all queries decreased from 7. Scale. Stinger improved Hive’s scalability in several ways.

Of course, the performance benefits delivered by Hive’s Vectorized Query engine allows you to process more data in less time. Less obvious perhaps, is the fact that using Tez means that Hive jobs, that used to require many distinct Map. Reduce jobs, are now processed in a single Tez job. In one extreme case, Query 8. Map. Reduce jobs to a single Tez job.

One other very valuable item was improvements to dynamic partitioning, making it much easier to load large amounts of data into large numbers of partitions in a single shot. Query 4. 9 joins a total of 6 fact tables. Query 9. 8, a data mining query returned more than 2.

GB of data and almost 7. Over the past year Hive has expanded its SQL capabilities tremendously, including windowing functions, subqueries, datatypes like CHAR and VARCHAR, and much more. Hive has by far the most comprehensive SQL support in the open source Hadoop ecosystem, along with the most certifications, the most integrations, and is proven as the most scalable and robust solution available natively in Hadoop.

Total of 5. 0 queries run, covering interactive, deep reporting, and data mining queries. Hive 0. 1. 0. 0 because windowing functions, sub- queries in IN clause, missing data types, and expanded JOIN syntax support were not supported. In keeping with complete openness, we provide you with detailed results on Slide. Share. For the most part, the cluster used the Ambari defaults (except where noted below).

The ratio is important because it minimizes disk thrash and maximizes throughput. Other Settings: yarn.

Default virtual memory for a job’s map- task and reduce- task were set to 4. Xmx. 38. 00m. Tez app masters were given 8 GBmapreduce. Xmx. 38. 00m. This is smaller than 4.

Note: . After data was generated, “hadoop balancer” was used to balance data across the cluster. A total of 5. 0 queries from the industry standard TPC- DS benchmark were run. Under Hive 0. 1. 3. In both cases, the average execution time was used as the official time. Under Hive 0. 1. 0. Despite this, the full suite took more than 7 days to fully execute. The reported time is the result of the single execution.

Comparing Benchmarks. There are a lot of published benchmarks that compare SQL options for Hadoop.

This is the near optimal ratio of processes to drives for a machine with the I/O bandwidth available from 6 HDDs. We recommend 1. 2x.

TB or 1. 2x. 4TB in production for better I/O bandwidth/throughput. Summary: Customers use Hive for complex query use cases and want the same data types and complexities of query semantics to work on large datasets as well as datasets more suitable to interactive use cases.
