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

1. Introduction The Spark-submit script in the Spark Bin directory is used to start the application on the cluster. You can use the Spark for all supported cluster managers through a unified interface, so you do not have to specifically configure your application for each cluster Manager (It can using all Spark ' s su

I just started to play with Cloudera Manager 5.0.1 and a small fresh setup cluster. It has six datanodes with a total capacity of 16.84 TB, one Namenode and another node for the Cloudera Manager and other S Ervices. From start on, I is wondering how to start the HDFS balancer. Short answer: To run the balancer your need to add the balancer role to any node in you cluster! I'll show you the few simple steps
