Marcus Eriksson updated CASSANDRA-18013: ---------------------------------------- Status: Ready to Commit (was: Review In Progress) +1 > Splitter sometimes creates different number of splits than requested > -------------------------------------------------------------------- > > Key: CASSANDRA-18013 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18013 > Project: Cassandra > Issue Type: Bug > Components: Local/Compaction > Reporter: Jacek Lewandowski > Assignee: Jacek Lewandowski > Priority: Normal > Fix For: 3.11.x, 4.1, 4.2, 4.x > > Time Spent: 10m > Remaining Estimate: 0h > > {{Splitter}} in some cases may produce one split more than requested. When it > happens, it fails with assertion error when assertions are enabled. > Test to reproduce the issue: > {code:java} > Splitter splitter = getSplitter(Murmur3Partitioner.instance); > long lt = 0; > long rt = 31; > Range<Token> range = new > Range<>(getWrappedToken(Murmur3Partitioner.instance, BigInteger.valueOf(lt)), > > getWrappedToken(Murmur3Partitioner.instance, BigInteger.valueOf(rt))); > for (int i = 1; i <= (rt - lt); i++) > { > List<Token> splits = splitter.splitOwnedRanges(i, > Arrays.asList(new Splitter.WeightedRange(1.0d, range)), false); > logger.info("{} splits of {} are: {}", i, range, splits); > Assertions.assertThat(splits).hasSize(i); > } > {code} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
