cassandra 2.0 catch 101 – part2

After playing playing around cassandra 2.0 for quite sometime and in this article, I'm gonna share with you a strange issue that encountered, unable to drop table no matter how.

I'm using the stress tools in cassandra package to create the table column family. It seem that the keyspaces and table created successfully. Following are the output.


Created keyspaces. Sleeping 1s for propagation.
total,interval_op_rate, interval_key_rate,latency,95th,99.9th,elapsed_time
..
..
..


So everything seem to created okay in cassandra.



cqlsh:system> desc keyspaces;

jw_schema1 system system_traces

cqlsh:system> use jw_schema1;
cqlsh:jw_schema1> desc tables;

Counter1 Counter3 Standard1 Super1 SuperCounter1

cqlsh:jw_schema1> desc table Counter1;

CREATE TABLE "Counter1" (
key blob,
column1 ascii,
value counter,
PRIMARY KEY (key, column1)
) WITH COMPACT STORAGE AND
bloom_filter_fp_chance=0.010000 AND
caching='KEYS_ONLY' AND
comment='' AND
dclocal_read_repair_chance=0.000000 AND
gc_grace_seconds=864000 AND
index_interval=128 AND
read_repair_chance=0.100000 AND
replicate_on_write='true' AND
populate_io_cache_on_flush='false' AND
default_time_to_live=0 AND
speculative_retry='NONE' AND
memtable_flush_period_in_ms=0 AND
compaction={'class': 'SizeTieredCompactionStrategy'} AND
compression={};

cqlsh:jw_schema1>




when selecting or dropping table in any tables within the keyspaces, things started to become wrong and cassandra server debug log show nothing wrong.

cqlsh:jw_schema1> select * from Counter1;
Bad Request: unconfigured columnfamily counter1

and using the datastax java binary driver.

public void connect(String node) {
    cluster = Cluster.builder().addContactPoint(node)
        .addContactPoints("127.0.0.1")
	.withRetryPolicy(DowngradingConsistencyRetryPolicy.INSTANCE)
	.withReconnectionPolicy(new ConstantReconnectionPolicy(100L)).build();
    session = cluster.connect("jw_schema1");

    ExecutionInfo info = session.execute("DROP TABLE Counter1").getExecutionInfo();
}

So I'm not sure what is gone wrong, but I'end up dropping the keyspace as a work around.

cqlsh:system> drop keyspace jw_schema1;
cqlsh:system>

---

work around

cqlsh:system> desc keyspaces;

TestKeyspace  system  system_traces

cqlsh:system> drop keyspace TestKeyspace;
Bad Request: Cannot drop non existing keyspace 'testkeyspace'.
cqlsh:system> drop keyspace "TestKeyspace";
cqlsh:system> desc keyspaces;

system  system_traces
