Log with my mentor :)
[10:16] <EugeneR> update method in HRegion is using TreeMap as it's parameter...
[10:17] <EugeneR> so... before run it.. we creating a TreeMap from our Set of
changes
[10:17] <EugeneR> and using comparator for sorting
[10:17] <EugeneR> but!
[10:17] <EugeneR> guess what update doing with TreeMap??? ))
[10:18] <EugeneR> updatesByColumn.entrySet()... it gets back our Set of changes
from that TreeMap!!! :)
[10:19] <EugeneR> we are wrapping Set in TreeMap to put in method and then get
it back in this method.... )
