Hello guys, I am reading the book "HBase, the definitive guide", at the beginning of chapter 3, it is mentioned in order to reduce performance impact for clients to update the same row (lock contention issues for automatic write), batch update is preferred. My questions is, for MR job, what are the batch update methods we could leverage to resolve the issue? And for API client, what are the batch update methods we could leverage to resolve the issue?
thanks in advance, Lin
