HiveServer2 allows multiple concurrent connections to the Hive server on the network. HiveServer2 is a patch for 0.9.0 basic version of the hive distributed to Apache Hadoop in MAPR. See Installing hive installation for more information. The mapr-Hive Pack includes HiveServer1 and HiveServer2, which you can choose to run. This page contains the following topics:

Installation and configuration of MapR distributed cluster and shell automation script The distributed cluster Installation Process of MapR is still very difficult, far from being planned. I have summarized the installation configuration. Because there are many machines in the cluster, It is very tiring to manually configure each server. I have compiled an automatic configuration script. The following descr

MAPR distributed cluster installation process is still very difficult, far from the simple Plan. I summarize the installation configuration, because the cluster has a lot of machines, manual each configuration is very tired, wrote an automated configuration script, the following script as the main line narrative (the script is not perfect, follow-up continues to improve).Scripting requires shell-based, and it's better to master the statistical tools o

Chapter 2 mapreduce IntroductionAn ideal part size is usually the size of an HDFS block. The execution node of the map task and the storage node of the input data are the same node, and the hadoop performance is optimal (Data Locality optimization, avoid data transmission over the network ). Mapreduce Process summary: reads a row of data from a file, map function processing, Return key-value pairs; the system sorts the map results. If there are multi
