Subject Re: Java api for connecting to hiveserver2
Date Sat, 11 Oct 2014 19:43:26 GMT
Sorry Anish, but being database programmer in the past, I always used
embedded SQL interface... I was wondering should we really need direct Java
interface w/ HiveServer2? May be I am wrong, but would like to know your
view on what are the limitations of using embedded SQL vs direct Java API.
