Ke Han updated CASSANDRA-18091: ------------------------------- Since Version: 4.0.6 > Column update lost after a full stop upgrade from 4.0.6 to trunk (4.2:fdc88a) > ----------------------------------------------------------------------------- > > Key: CASSANDRA-18091 > URL: https://issues.apache.org/jira/browse/CASSANDRA-18091 > Project: Cassandra > Issue Type: Bug > Reporter: Ke Han > Priority: Normal > > When we performed a full-stop upgrade from release 4.0.6 to 4.2 trunk > (fdc88a), we executed the same read command before and after the upgrade and > found that some column updates were lost after the upgrade. > This inconsistency is likely related to timing and cannot be reproduced > deterministically. Though it's non-deterministic, this failure *happens > reliably* *once every ten times* when executing the following command > sequence. > h2. Steps to reproduce > 1. Set up a 4.0.6 3-node cluster. (N0: seed node, N1, N2). Default > configurations, set num_tokens to 256. > 2. Execute the following cqlsh command > (The test commands use random parameters because it is generated by our > testing tool) > {code:java} > CREATE KEYSPACE uuid5f86250110a247d48c481c5579cb2ea1 WITH REPLICATION = { > 'class' : 'SimpleStrategy', 'replication_factor' : 1 }; > CREATE TABLE uuid5f86250110a247d48c481c5579cb2ea1.kattmG (kattmG TEXT,VldG > TEXT,Ajqm TEXT,lTQSQ INT,EVzlSKrbkUGyhJshH TEXT, PRIMARY KEY (lTQSQ )); > DELETE FROM uuid5f86250110a247d48c481c5579cb2ea1.kattmG WHERE lTQSQ = 2; > ALTER TABLE uuid5f86250110a247d48c481c5579cb2ea1.kattmG DROP kattmG ; > INSERT INTO uuid5f86250110a247d48c481c5579cb2ea1.kattmG (Ajqm, > EVzlSKrbkUGyhJshH, lTQSQ) VALUES > ('nZJzNjYnXOwPLpVoFSVwxcvznsDFBYqmlprrVXYJQLzYvYkrmfEsiuAcCtggypnxIkIevRHyPQGOWrIZNObJ','RaAhbVKUQzgJaupaupKPVnNLLYDaZEaMyFteVwhLePqZwikuBEsVDxTuTqBfkFYmeMMsOFXjVkObZduPfAFsLzuYlrgpYsPPxDNQCRzzPaEdWHARnnWbAFAUUnbYnvEESeHDRHSkEhSnoREprrHWasYLMSocIYiMGQXjzsaKptqbtPgrztIdpQLgDAZOPfhJIblmwTFAWiFbzrbTkFwJGP',1693380861); > DELETE FROM uuid5f86250110a247d48c481c5579cb2ea1.kattmG WHERE lTQSQ = > 1693380861; > INSERT INTO uuid5f86250110a247d48c481c5579cb2ea1.kattmG (lTQSQ) VALUES (2); > ALTER TABLE uuid5f86250110a247d48c481c5579cb2ea1.kattmG DROP VldG ; > INSERT INTO uuid5f86250110a247d48c481c5579cb2ea1.kattmG (lTQSQ) VALUES > (1693380861); > INSERT INTO uuid5f86250110a247d48c481c5579cb2ea1.kattmG (Ajqm, lTQSQ) VALUES > ('ldrsHa',1693380861); > ALTER TABLE uuid5f86250110a247d48c481c5579cb2ea1.kattmG DROP Ajqm ;{code} > 3.
