Re: HTablePool is deprecated, any alternatives?

You are right Li Li. HTablePool was deprecated in 0.94, 0.95/0.96, and removed in 0.98: See: https://issues.apache.org/jira/browse/HBASE-6580 Use HConnection instead: http://comments.gmane.org/gmane.comp.java.hadoop.hbase.devel/38950 2014-02-12 22:13 GMT-04:30 Li Li : > I am using hbase 0.94.11.
