我是一名卡桑德拉新手。我在Cassandra cqlsh 5.0.1中看到以下错误Cassandra 2.1.2 | CQL规范3.2.0
以下是我在使用sstableloader时看到的错误：
./sstableloader -d <hostname> -u <user> -pw <pass> <filename>

奇怪的是，我仅针对特定键空间获得此错误。当我创建一个新的密钥空间（使用与问题密钥空间完全相同的命令并尝试sstableloader时，我没有看到同样的问题。当我设置DEBUG日志级别时，我看到以下内容：
DEBUG [Thrift:1] 2015-02-20 00:32:38,006 CustomTThreadPoolServer.java:212 - Thrift transport error occurred during processing of message.

不确定这是否真的是一个错误，因为根据某些在线链接，我发现无论在设置调试日志级别时都会显示此消息
答案 0 :(得分：0)
我正在尝试使用Cassandra 2.1.8。您看到的错误是这块Cassandra代码的产物：
try
{
// Query endpoint to ranges map and schemas from thrift
InetAddress host = hostiter.next();
Cassandra.Client client = createThriftClient(host.getHostAddress(), rpcPort, this.user, this.passwd, this.transportFactory);
setPartitioner(client.describe_partitioner());
Token.TokenFactory tkFactory = getPartitioner().getTokenFactory();
for (TokenRange tr : client.describe_ring(keyspace))
{
Range<Token> range = new Range<>(tkFactory.fromString(tr.start_token), tkFactory.fromString(tr.end_token), getPartitioner());
for (String ep : tr.endpoints)
{
addRangeForEndpoint(range, InetAddress.getByName(ep));
}
}
String cfQuery = String.format("SELECT * FROM %s.%s WHERE keyspace_name = '%s'",
Keyspace.SYSTEM_KS,
SystemKeyspace.SCHEMA_COLUMNFAMILIES_CF,
keyspace);
CqlResult cfRes = client.execute_cql3_query(ByteBufferUtil.bytes(cfQuery), Compression.NONE, ConsistencyLevel.ONE);
for (CqlRow row : cfRes.rows)
{
String columnFamily = UTF8Type.instance.getString(row.columns.get(1).bufferForName());
String columnsQuery = String.format("SELECT * FROM %s.%s WHERE keyspace_name = '%s' AND columnfamily_name = '%s'",
Keyspace.SYSTEM_KS,
SystemKeyspace.SCHEMA_COLUMNS_CF,
keyspace,
columnFamily);
CqlResult columnsRes = client.execute_cql3_query(ByteBufferUtil.bytes(columnsQuery), Compression.NONE, ConsistencyLevel.ONE);
CFMetaData metadata = CFMetaData.fromThriftCqlRow(row, columnsRes);
knownCfs.put(metadata.cfName, metadata);
}
break;
}
catch (Exception e)
{
if (!hostiter.hasNext())
throw new RuntimeException("Could not retrieve endpoint ranges: ", e);
}
因此，您所拥有的是在消息中汇总的各种错误，“无法检索端点范围”。如果没有下载Cassandra源代码并通过它进行调试，您将无法分辨出具体的错误。这就是我做的。
我的架构是使用https://github.com/DonBranson/cql_schema_versioning在多步骤过程中构建的。一步就是这样：
ALTER TABLE user_reputation DROP ban_votes;
DROP触发Cassandra BulkLoader错误，该错误会打印您看到的错误消息。但是，无数其他错误条件显示相同的消息。错误消息绝对没有帮助我们真正解决问题。
我还发现，如果您正在加密这样的节点间通信，那么BulkLoader将无法工作：
internode_encryption: all
因此，在我正在运行的DigitalOcean云中，我必须加密internode comm，它会失败，但至少会显示一条指示连接失败的消息：
