Description

While working on HBASE-19163, some unittest failures exposes an interesting issue.
When client sends a batch, at the region server, it can be divided into multiple minibatchs. If one of minibatches runs into some exception(resource for an example), the exception gets back to the client and it thinks that the whole batch fails. The client will send the whole batch again will cause the already-succeeded minibatches to be processed again. We need to have mechanism to allow partial success of the batch.
