A luxurious provision for the developers for running a user friendly SQL query on Hadoop Distributed File System (HDFS) and Hbase. Hive also provides an SQL like interface, for following the batch processing that lead to lags if something is looking for performance oriented alternative. This lag has been overcome for running queries in real time that allows integration of SOL BI tools with Hadoop data store.

An open source tool like Impala backs up the popular formats like LZO,Avro, RCFile, sequenceFile etc. A cloud based architecture through Amazon’s Elastic MapReduce.
