Apache Impala and Presto are both open source tools. Support Questions Find answers, ask questions, and share your expertise cancel. 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. 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. A relational database is a digital database based on the relational model of data, as proposed by E. F. Codd in 1970. Some purists refer to these as Pseudo Relational Database Management Systems (PRDBMS), while referring to any DBMS that satisfies all of the Codd’s 12 rules as being a Truely-Relational Database Manageme… Although the most popular DBMSs are of the relational model, few commercial RDBMSs actually adhere to all of Codd’s 12 rulesof a relational database management system (note that “Codd’s 12 rules” is actually thirteen rules, starting at zero). HBase vs Impala. Many relational database systems have an option of using the SQL (Structured Query Language) for querying and maintaining the database. To avoid this latency, Impala avoids Map Reduce and access the data directly using specialized distributed query engine similar to RDBMS.
