What is Hive Metastore.

Apache Hive is a client side library providing a table like abstraction on top of the data in HDFS for data processing. Hive jobs are converted into a MR plan which is then submitted to the Hadoop cluster for execution. The Hive table definitions and mapping to the data are stored in a metastore.
