-----------------------------------------------------------
I notice that HConnection can drop data, if HBase is down and ChukwaHBaseStore
may not receive exception message to be notified of HBase write error. We are
adopting new API because HTablePool API is scheduled for removal in HBASE-9117.
In HTablePool, exception is thrown correctly. Hence, adoption of new HBase
API will need to work with HBase community that HConnection can drop data.
This is related to HBASE-11306. We probably need to settle on the version of
HBase that we support in Chukwa 0.7.0. If we are skipping HBase 0.96-0.98,
maybe we should jump directly to 0.99.2, if HConnection to see if connection
pool api has been improved.

> Project: Chukwa
> Issue Type: Improvement
> Components: Data Collection
> Affects Versions: 0.6.0

>
> With 0.94 onwards, new HBase APIs are available, while depreciating old ones.
> For example, HTablePool has been depreciated and will be removed in the next
> release ( probably in 0.99), and HConnection is new one we should be using.
> Similarly, the KeyValue has been replaced with Cell APIs. We should change
> Chukwa code to have these new APIs.
