Devaraj Das updated HBASE-11214:
--------------------------------

    Attachment: 11214-1.txt

This introduces another pool for handling "close" of scanners. Earlier the 
close calls would be in the same pool and would cause issues when tasks in the 
pool are cancelled (we don't want to actually cancel the tasks scheduled for 
doing "close"). We'd also need to be aware of what type of tasks complete when 
a task in the pool completes and handle it accordingly... Having a separate 
pool simplifies handling these issues.
I also removed some unused constructors in 
ClientScanner/SmallScanner/ReverseScanner and changed the annotation to Private 
on those classes.
