The tablet of concern has 2000 tablets while all others have 1000 so it looks like the balancers aren't evening out the tablets per node as expected.
Is there a way to force the balancer to run or rectify this situation by moving tablets to alternate nodes?

The balancers that ship with accumulo attempt to keep an equal number of tablets on each server. An empty tablet, will be balanced with the same weight as a 50G tablet.
You can write a new balancer to take advantage of the properties of the tablets, and any expected hotspots you have.

We are seeing a single server that has less entries than all the other nodes in the cluster. Accumulo now appears to be directing higher ingest tablets to this node and its now getting 7 times the ingest entries than all other nodes and is slowing or load. Does Accumulo attempt to balance disk usage across the nodes for a table by moving tablets and that is why we are seeing this node ingesting more?
If not, is it possible to make accumulo rebalance the ingest across all servers during a load?
