[jira] [Commented] (HBASE-15554) StoreFile$Writer.appendGeneralBloomFilter generates extra KV

    [ https://issues.apache.org/jira/browse/HBASE-15554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15396919#comment-15396919 ] 

ramkrishna.s.vasudevan commented on HBASE-15554:
------------------------------------------------

Apart from the Key Interface (which we may need) will first rework the StorefileWrite#appendGeneralBloomFilter() to work with offheap cells and with ROW and ROWCOL blooms in a better way. So that later it is easy to verify this code
