> When we use the TRUNCATE command to delete all data in the table, the deleted
> data come back after a node restart or upgrade. This problem happens at the
> latest releases (2.2.19, 3.0.28, or 4.0.7)
> h1. Steps to reproduce
> h2. To reproduce it at release (3.0.28 or 4.0.7)
> Start up a single Cassandra node. Using the default configuration and execute
> the following cqlsh commands.
> {code:java}
> CREATE KEYSPACE IF NOT EXISTS ks WITH REPLICATION = { 'class' :
> 'SimpleStrategy', 'replication_factor' : 1 };
> CREATE TABLE ks.tb (c3 TEXT,c4 TEXT,c2 INT,c1 TEXT, PRIMARY KEY (c1, c2, c3
> ));
> INSERT INTO ks.tb (c3, c1, c2) VALUES ('val1','val2',1);
> CREATE INDEX IF NOT EXISTS tb ON ks.tb ( c3);
> TRUNCATE TABLE ks.tb;
> DROP INDEX IF EXISTS ks.tb; {code}
> Execute a read command
> {code:java}
> cqlsh> SELECT c2 FROM ks.tb;
> c2
> ----
> (0 rows) {code}
> Then, we flush the node and kill the Cassandra daemon by
> {code:java}
> bin/nodetool flush
> pgrep -f cassandra | xargs kill -9 {code}
> We restart the node. When the node has started, perform the same read, and
> the deleted data comes back again.
> {code:java}
> cqlsh> SELECT c2 FROM ks.tb;
> c2
> ----
> 1
> (1 rows) {code}
> h2. To reproduce it at release (2.2.19)
> We don't need to kill the Cassandra daemon. Use bin/nodetool stopdaemon is
> enough. The other steps are the same as reproducing it at 4.0.7 or 3.0.28.
> {code:java}
> bin/nodetool -h ::FFFF:127.0.0.1 flush
> bin/nodetool -h ::FFFF:127.0.0.1 stopdaemon{code}
>
> I have put the full log to reproduce it for release 4.0.7 and 2.2.19 in the
> comments.
