Jason Brown commented on CASSANDRA-13899: ----------------------------------------- tbh, I don't think it's large partitions that necessarily triggered this bug; streaming just transfers the bytes of sstable Data file naively. I think it was something in the dataset and the way it compresses that exposed the bug. Thus, I'm not sure how to proceed with a dtest, especially one based on [~pauloricardomg]'s submitted patch (as highly useful as it is!). > Streaming of very large partition fails > ---------------------------------------- > > Key: CASSANDRA-13899 > URL: https://issues.apache.org/jira/browse/CASSANDRA-13899 > Project: Cassandra > Issue Type: Bug > Reporter: Paulo Motta > Assignee: Jason Brown > Fix For: 4.0 > > Attachments: largepartition.yaml > > > Streaming a single partition with ~100K rows fails with the following > exception: > {noformat} > ERROR [Stream-Deserializer-/127.0.0.1:35149-a92e5e12] 2017-09-21 04:03:41,237 > StreamSession.java:617 - [Stream #c2e5b640-9eab-11e7-99c0-e9864ca8da8e] > Streaming error occurred on session with peer 127.0.0.1 > org.apache.cassandra.streaming.StreamReceiveException: > java.lang.RuntimeException: Last written key > DecoratedKey(-1000328290821038380) >= current key > DecoratedKey(-1055007227842125139) writing into > /home/paulo/.ccm/test/node2/data0/stresscql/typestest-482ac7b09e8d11e787cf85d073c > 8e037/na-1-big-Data.db > at > org.apache.cassandra.streaming.messages.IncomingFileMessage$1.deserialize(IncomingFileMessage.java:63) > ~[main/:na] > at > org.apache.cassandra.streaming.messages.IncomingFileMessage$1.deserialize(IncomingFileMessage.java:41) > ~[main/:na] > at > org.apache.cassandra.streaming.messages.StreamMessage.deserialize(StreamMessage.java:55) > ~[main/:na] > at > org.apache.cassandra.streaming.async.StreamingInboundHandler$StreamDeserializingTask.run(StreamingInboundHandler.java:178) > ~[main/:na] > at java.lang.Thread.run(Thread.java:745) [na:1.8.0_121] > {noformat} > Reproduction steps: > * Create CCM cluster with 2 nodes > * Start only first node, disable hinted handoff > * Run stress with the attached yaml: {{tools/bin/cassandra-stress "user > profile=largepartition.yaml n=10K ops(insert=1) no-warmup -node whitelist > 127.0.0.1 -mode native cql3 compression=lz4 -rate threads=4 -insert > visits=FIXED(100K) revisit=FIXED(100K)"}} > * Start second node, run repair on {{stresscql}} table - the exception above > will be thrown. > I investigated briefly and haven't found anything suspicious.
