The compiler responses to the metadata request are sent to the metaStor...
A hive can operate in two modes based on the number of data nodes in Hadoop. 1. Local mode 2. Map-reduce mode When using Local mode: 1. We can run Hive in pseudo mode if Hadoop is installed under pseudo mode with one data node. 2. In this mode, we can have a data size of up to one machine as long as it is smaller in terms of physical size. 3. Small...
