RDBMS; DBMS stores data as file. Cloudera Impala is an excellent choice for programmers for running queries on HDFS and Apache HBase as it doesn’t require data to be moved or transformed prior to processing. Data is stored in the form of tables which are related to each other. Hive can be also a good choice for low latency and multiuser support requirement. Watch Queue Queue There is always a question occurs that while we have HBase then why to choose Impala over HBase instead of simply using HBase. Most RDBMSs satisfy some of Codd’s rules but not all. Given the benefits of Impala why would one ever use Hive ? So to clear this doubt, here is an article “HBase vs Impala: Feature-wise Comparison”. As an example Hive and Impala are very particular about the timestamp format that they recognize and support, one workaround to avoid such bad records is to use a trick where rather than specifying the data type as timestamp, you specify the datatype as String and then use the cast operator to transform the records to timestamp format, this way bad records are skipped and the query does not error out. Hive Vs Impala: 1. Note the use of window function row_number and ordering by truncated timestamp, and cast operator to avoid invalid records. Data elements need to access individually.
