Subject [jira] [Commented] (CHUKWA-723) Update Chukwa code to use new HBase API available in 0.94
Date Sun, 11 Jan 2015 20:22:34 GMT


Eric Yang commented on CHUKWA-723:

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 Connection
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.

> 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.
