Install the version of eclipse that comes with Ubuntu repo (for 12.04 its eclipse 3.8)Then follow the below steps to update that version with the latest eclipse.

Why OpenTSDB chose HBase for Time Series data storage? - Stack Overflow

Why OpenTSDB chose HBase for Time Series data storage? - Stack Overflow:

Nice reply to this question by OpenTSDB author for why StumbleUpon uses HBase (and in fact facebook does the same for big data analytics):

I chose HBase because it scales. Whisper is much like RRD, it's a fixed-size database, it must destroy data in order to work within its space constraints. HBase offers the following properties that make it very well suited for large scale time series databases:
Linear scaling. Want to store data? Add more nodes. At StumbleUpon, where I wrote OpenTSDB, our time series data was co-located on a 20-node cluster that was primarily used for analytics and batch processing. The cluster grew to 120 nodes fairly quickly, and meanwhile OpenTSDB, which makes up only a tiny fraction of the cluster's workload, grew to half a trillion data points.Automatic replication. Your data is stored in HDFS, which by default means 3 replicas on 3 different machines. If a machine or a drives dies…
