COMPLETE	merge is complete, the resulting tablet can be brought online, remove the marker in zookeeper
MERGING	when the number of chopped, offline tablets equals the number of merge tablets, begin the metadata updates
NONE	Not merging
SPLITTING	put all matching tablets online, split tablets if we are deleting
STARTED	created, stored in zookeeper, other merges are prevented on the table
WAITING_FOR_CHOPPED	after the tablet server chops the file, it marks the metadata table with a chopped marker
WAITING_FOR_OFFLINE	when the number of chopped tablets in the range matches the number of online tablets in the range, take the tablets offline
