Description:
While trying to use LossyCounting for HBASE-15519 , found following bugs in
current implementation
– Remove synchronization block from MetaTableMetrics to avoid congestion at
the code
– Fix license format
– Fix LossyCounting algorithm as per [http://www.vldb.org/conf/2002/S10P03.pdf
|http://www.vldb.org/conf/2002/S10P03.pdf]
-- Avoid doing sweep on every insert in LossyCounting
– Remove extra redundant data structures from MetaTableMetrics.
