Subject [jira] [Updated] (HBASE-12222) FuzzyRowFilter unpredictable with jagged rowkeys
Date Fri, 10 Oct 2014 01:21:33 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12222?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nick Dimiduk updated HBASE-12222:
---------------------------------
    Description: 
FuzzyRowFilter getNextCellHint doesn't take into account jagged rowkeys and produces surprising
results. For example, given a table of

{noformat}
0
0/0
0/1
0/2
1
1/0
1/1
1/2
2
2/0
2/1
2/2
{noformat}

and FuzzyPrefixFilter like "?/2", {1, 0, 0}

I would expect

{noformat}
0/2
1/2
2/2
{noformat}

The results include the rows '0', '1', and '2'

  was:
FuzzyRowFilter getNextCellHint doesn't take into account jagged rowkeys, thus it will skip
too far ahead. For example, given a table of

{noformat}
0
0/0
0/1
0/2
1
1/0
1/1
1/2
2
2/0
2/1
2/2
{noformat}

and FuzzyPrefixFilter like "?/2", {1, 0, 0}

I would expect

{noformat}
0/2
1/2
2/2
{noformat}

The results include the rows '0', '1', and '2'
