[jira] Commented: (HBASE-1906) FilterList of prefix and columnvalue not working properly with deletes and multiple values

["stack (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-1906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12765412#action_12765412 ] 

stack commented on HBASE-1906:
------------------------------

@jgray What seems to be happening is that we can exit the loop in HRegion#nextInternal without a call to filterRow.  W/o this call, stuff is left in when we exit via:

{code}
        if (filter != null && filter.filterRowKey(row, 0, row.length)) {
          if (!results.isEmpty() && !Bytes.equals(currentRow, row)) {
            return true;
          }
{code}

Its as though this test should be done first:

{code}
        if (!Bytes.equals(currentRow, row)) {
{code}

... before we see if a row should be filtered out based off row key.

If filtered out by filterRowKey, then need to run filterRow on results already accumulated somehow.

Will keep digging but input if any appreciated.

That deletes can come out of the peek seems fine after looking at it some...
