Xu Yao updated KUDU-2437:
-------------------------
Description: (was: When reading data in a kudu table using spark, if
there is a large amount of data in the tablet, reading the data takes a long
time.
The reason is that KuduRDD uses a tablet to generate the scanToken, so a spark
task needs to process all the data in a tablet. So:
# TS report the DRS bounds info to Master
# Client get the bounds info from Master
# Client generate the scanToken by bounds info of tablet（set
LowerBoundPrimaryKey and UpperBoundPrimaryKey）)
> Split a tablet into some chunks by size
