Performance is probably the largest difference between Accumulo and HBase.

Accumulo can ingest/scan at a rate of 800K entries/sec/node.
This performance scales well into the hundreds of nodes to deliver
100M+ entries/sec.

There are no recent HBase benchmarks and none in the peer-reviewed literature.
Old data suggests that HBase performance is ~1% of Accumulo performance.

In short, one can often replace a 20+ node database with
a single node Accumulo database.
