hello, i am a freshman with Hbase ,now i do the performace test with hbase in our project.
i use scan api to scan a table with filters. because we need the good performance ,so we scan
each region with a single thread , total 24 regions, so we start 24 scan task to scan . each
scan task we get a scanner to scan .

but now i have a exception below:
