ASF subversion and git services commented on ACCUMULO-1994: ----------------------------------------------------------- Commit 27ee2367056e5ad0cb6175f91154cd13d49e2c95 in branch refs/heads/master from [~ecn] [ https://git-wip-us.apache.org/repos/asf?p=accumulo.git;h=27ee236 ] ACCUMULO-1993 ACCUMULO-1994 make proxy useful for ruby, fix getRowRange (and test it) > proxy does not handle Key timestamps correctly > ---------------------------------------------- > > Key: ACCUMULO-1994 > URL: https://issues.apache.org/jira/browse/ACCUMULO-1994 > Project: Accumulo > Issue Type: Bug > Components: proxy > Affects Versions: 1.4.4, 1.5.0 > Reporter: Brian Loss > Assignee: Eric Newton > Fix For: 1.4.5, 1.5.1, 1.6.0 > > > The proxy thrift IDL does not declare any default values for the Key struct. > This means that timestamp will default to 0. However, in Java it defaults to > Long.MAX_VALUE. This means that ranges created through the proxy may behave > differently than ranges created in Java. For example, say in Ruby I create a > range as follows > {code} > range = Range.new(:start => Key.new(:row => "row1"), :startInclusive => true, > :stop => Key.new(:row => "row2"), :stopInclusive => true) > {code} > This range will not include any keys in row1 that don't have a column family, > qualifier, or visibility since timestamp of 0 sorts last. If I created the > same range in Java, those keys would be included. > Change the thrift IDL to declare 0x7FFFFFFFFFFFFFFF (Long.MAX_VALUE) as the > default value for timstamp so that the thrift-generated Key class behaves the > same way as the Java version. > [~kturner] pointed me to the getRowRange helper method on the AccumuloProxy > service. This method helps in some cases, but not the case I mentioned above > since I have two arbitrary rows. Also, in looking through the code in > ProxyServer, Keith noticed that the code does not seem to handle timestamps > correctly. For example, the getRowRange method does not pass a timestamp at > all (not even the EMPTY value). Also, the internal helper method getProxyKey > ignores the timestamp on the incoming key. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
