Martin Fransson created CASSANDRA-7801: ------------------------------------------
Summary: A successful INSERT with CAS does not always store data in the DB after a DELETE Key: CASSANDRA-7801 URL: https://issues.apache.org/jira/browse/CASSANDRA-7801 Project: Cassandra Issue Type: Bug Components: Core Environment: PC with Windows 7 and on Linux installation. Have seen the fault on Cassandra 2.0.9 and Cassandra 2.1.0-rc5 Reporter: Martin Fransson Attachments: cas.zip When I run a loop with CQL statements to DELETE, INSERT with CAS and then a GET. The INSERT opertion is successful (Applied), but no data is stored in the database. I have checked the database manually after the test to verify that the DB is empty. for (int i = 0; i < 10000; ++i) { try { t.del(); t.cas(); t.select(); } catch (Exception e) { System.err.println("i=" + i); e.printStackTrace(); break; } } myCluster = Cluster.builder().addContactPoint("localhost").withPort(12742).build(); mySession = myCluster.connect(); mySession.execute("CREATE KEYSPACE IF NOT EXISTS castest WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };"); mySession.execute("CREATE TABLE IF NOT EXISTS castest.users (userid text PRIMARY KEY, name text)"); myInsert = mySession.prepare("INSERT INTO castest.users (userid, name) values ('user1', 'calle') IF NOT EXISTS"); myDelete = mySession.prepare("DELETE FROM castest.users where userid='user1'"); myGet = mySession.prepare("SELECT * FROM castest.users where userid='user1'"); } I can reproduce the fault with the attached program on a PC with windows 7. You need a cassandra runing and you need to set the port in the program. -- This message was sent by Atlassian JIRA (v6.2#6252)
