Implementation

Hue is a web application which helps to browse HDFS and work with Hive and Cloudera Impala queries, MapReduce jobs.

Creation of tables in Hcatalog:

Hive and Beeswax

Hive is an infrastructure built on top of Hadoop for data summarization, query and analysis

Beeswax an application to perform HIVE queries

Processing in Beeswax:

Total no and rank of crime type –

select primary_type, count(iucr), rank() over (ORDER BY count(iucr) desc) from crime group by primary_type limit

100;

Queries and Visualization

number of crime as per location type for a given area- select location_description, count(iucr) from crime where address = '008XX N MICHIGAN AVE' group by location_description limit 100;
