我执行我的表中的一些查询，当我执行这个查询：读取失败卡桑德拉
select o_type from basic_data where oid4 = 1;
我从卡桑德拉这样的回答：
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，当我执行此查询：
select o_type from basic_data where oid4 = 12192;
我有什么，我应该得到：
o_type
----------------------------------------------------------------
otype:G ,otype_bin:-268435456;otype:GiC,otype_bin:-234881024;
我不知道为什么我只能在某些行执行查询时，你有一些建议？
