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

Services:haddoop components that can be deployed on cluster, such as Hdfs,yarn,hbase.Roles: When the service is configured, it is created by Cloudera Manager. For example, Namenode is a role of the HDFs service.Role group: The management of role can divide the same category of roles (such as datanode) into different role groups. Each role group can have its own series of configurations.Role Instance: A single instance (which can be considered a proces

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
