cloudera manager

Cloudera impala is an engine that runs distributed queries on HDFS and hbase.This source is a snapshot of our internal development version. We regularly update the version.This readme document describes how to use this source to build cloudera Impala.

Impala is a new query system developed by cloudera. It provides SQL semantics and can query Pb-level big data stored in hadoop HDFS and hbase. Although the existing hive system also provides SQL semantics, the underlying hive execution uses the mapreduce engine and is still a batch processing process, which is difficult to satisfy the query interaction. In contrast, Impala's biggest feature is its speed. Impala provides a real-time SQL query interface

Before doing so, make sure you have the ODI software installed and build a Hadoop environment, or you can refer to my other blog posts to build the environment.1.

To standardize hadoop configurations, cloudera can help enterprises install, configure, and run hadoop to process and analyze large-scale enterprise data. For enterprises, cloudera's software configuration does not use the latest hadoop 0.20, but uses hadoop 0.18.3-12. cloudera. ch0_3 is encapsulated and integrated with hive provided by Facebook, pig provided by Yahoo, and other hadoop-based SQL implementa
