Xiang Li updated HBASE-17254: ----------------------------- Description: In KeyValue(and there might be other ExtendedCell implementations), heapOverhead() does not do alignment(padding gap). I think alignment is required when calculating heapOverhead, because the space losses due to alignment can not be used by other objects in heap. (was: In KeyValue(and there might be other ExtendedCell implementations), heapOverhead() does not do alignment(padding gap). I think alignment is required when calculating heapOverhead, as the space losses due to alignment can not be used by other objects in heap.) > Do alignment in heapOverhead() for ExtendedCell implementations > --------------------------------------------------------------- > > Key: HBASE-17254 > URL: https://issues.apache.org/jira/browse/HBASE-17254 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Xiang Li > Assignee: Xiang Li > Priority: Critical > > In KeyValue(and there might be other ExtendedCell implementations), > heapOverhead() does not do alignment(padding gap).
