【问题描述】：
我正在对我的表执行一些查询，当我执行这个查询时：
select o_type from basic_data where oid4 = 1;
我从 Cassandra 那里得到了这个答案：
Traceback (most recent call last):
File "/usr/bin/cqlsh.py", line 1277, in perform_simple_statement
result = future.result()
File "cassandra/cluster.py", line 3822, in cassandra.cluster.ResponseFuture.result (cassandra/cluster.c:74332)
raise self._final_exception
ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read] message="Operation failed - received 0 responses and 1 failures" info={'failures': 1, 'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}
但是当我执行这个查询时：
select o_type from basic_data where oid4 = 12192;
我有我应该得到的东西：
o_type
----------------------------------------------------------------
otype:G ,otype_bin:-268435456;otype:GiC,otype_bin:-234881024;
我不知道为什么我只能对某些行执行查询，您有什么建议吗？
编辑：
我的 system.log 中有错误

尝试使用跟踪进行查询并将跟踪粘贴到您的问题中。也许是因为墓碑
