Frank vissing updated CASSANDRA-19747:
--------------------------------------
Description:
After dropping at least 2 fields the schema.cql produced by _nodetool snapshot_
is invalid (it is missing a comma)
{code:sql}
CREATE TABLE IF NOT EXISTS test.testtable (
field1 text PRIMARY KEY,
field2 text
field3 text
) WITH ID ...{code}
expected outcome
{code:sql}
CREATE TABLE IF NOT EXISTS test.testtable (
field1 text PRIMARY KEY,
field2 text,
field3 text
) WITH ID ...{code}
reproducing the isue is simple by running the following commands
{code:sh}
docker run -d --name cassandra cassandra:4.1.5
echo "Wait for the container to start"
until docker exec -ti cassandra nodetool status | grep UN;do sleep 1;done;sleep
10
echo "Create keyspace and table for test"
docker exec -ti cassandra cqlsh -e "CREATE KEYSPACE IF NOT EXISTS test WITH
replication = {'class': 'SimpleStrategy', 'replication_factor': '1'}; CREATE
TABLE IF NOT EXISTS test.testtable (field1 text PRIMARY KEY,field2 text,field3
text);"
echo "Drop 2 fields"
docker exec -ti cassandra cqlsh -e "ALTER TABLE test.testtable DROP (field2,
field3);"
echo "Create snapshot and view schema.cql"
docker exec -ti cassandra /opt/cassandra/bin/nodetool snapshot -t my_snapshot
docker exec -ti cassandra find /var/lib/cassandra/data -name schema.cql -exec
cat {} + {code}
the full output of the sql generated by the reproduce is below
{code:sql}
CREATE TABLE IF NOT EXISTS test.testtable (
field1 text PRIMARY KEY,
field2 text
field3 text

Found this bug while trying to restore the schema from a backup created by
copying a snapshot from a running node.
