Firstly it was. But predicate is for reading and it could be implemented for read only factories(HBaseKeyFactory). So I thought it would be better to split predicate handler from key factory. I'll add some comments. > On March 7, 2014, 6:22 a.m., Xuefu Zhang wrote: > > hbase-handler/src/java/org/apache/hadoop/hive/hbase/HBaseCompositeKey.java, > > line 116 > > <https://reviews.apache.org/r/18179/diff/4/?file=513313#file513313line116> > > > > I saw the same method, but defined in several different classes.

If Swarnim allows the filter logic to be moved into factory, this can be removed. > On March 7, 2014, 6:22 a.m., Xuefu Zhang wrote: > > hbase-handler/src/java/org/apache/hadoop/hive/hbase/HBaseStorageHandler.java, > > line 407 > > <https://reviews.apache.org/r/18179/diff/4/?file=513318#file513318line407> > > > > Because HBaseCompositeKey has a default implementation (return null) > > for decomposePredicate(), it seems this creates a different behavior as > > subsquenct code will not be exercised. Right. I should implement default behavior in HBaseCompositeKey. - Navis ----------------------------------------------------------- This is an automatically generated e-mail.
