To add to what Andy said - the key to getting HBase running well in AWS is:
1. Choose the right instance types. I usually recommend the HPC
instances or now the high storage density instances. Those will give
you the best performance.
2. Use the latest Amzn Linux AMIs and the latest HBase and HDFS
versions that work with each other.
3. Tune HBase for your workload. This you have to do anyway but HBase
on AWS is less forgiving as compared on on premise.
I've personally tested upto 10k req/sec/server writing 1K payloads on
HBase 0.92 (that's old!) on HPC instances.
