The columns option is independent of which columns you are fetching. If you fetch the columns specified in the columns option, those columns will be combined, while other fetched columns will not. > SummingCombiner does not adhere to Combiner#COLUMNS_OPTION > ---------------------------------------------------------- > > Key: ACCUMULO-2539 > URL: https://issues.apache.org/jira/browse/ACCUMULO-2539 > Project: Accumulo > Issue Type: Bug > Components: client > Affects Versions: 1.4.4, 1.5.1 > Reporter: Josh Elser > Assignee: Josh Elser > Fix For: 1.4.5, 1.5.2, 1.6.1 > > > In testing out the SummingCombiner, I set the Combiner#COLUMNS_OPTION which led me to believe that the SummingCombiner would limit columns to the set that is provided as an option through the IteratorSetting. > In practice, this was not the case as Combiner#findTop isn't used, and thus that column list is not adhered to. I can get the expected functionality out of SummingCombiner by calling {{ScannerBase#fetchColumn}} or {{ScannerBase#fetchColumnFamily}}. -- This message was sent by Atlassian JIRA (v6.2#6252)
