Schema evolution in hive tables

2016-12-07 Thread Rajat Khandelwal
behaviour or am I missing something obvious? Coming back to the question of schema evolution, as business usecases grow, there is a need to add fields in the table. So am I restricted by hive to add my fields at the end only? Thanks -- Rajat Khandelwal Software Engineer
