Hi,
You might want to write a class which implements HbaseEventSerializer. To test, SimpleHbaseEventSerializer might fit your needs. Using timestamps as keys will create hotspots. As such it's recommended you "bucket" so that each write is hitting say 1 of 32 buckets. Each agent would be configured as follows:
...rowPrefix = bucket
...suffix = timestamp
