Question about regions splitting
I have a question about how regions split.
Let's say we have a 2GB region and upon splitting the region will be
splitted into two 1GB sub-regions.
My first question is: will the two 1GB sub-regions always be on the same
host as the parent region?
My second question is: Let's say the HDFS block size is 64MB, then one 1GB
region will contains about 16 HDFS blocks, will all HDFS blocks always be
on the same host as the region?
