cassandra - 读失败Cassandra

我正在我的桌子上执行一些查询，当我执行此查询时：

select o_type from basic_data where oid4 = 1;

我有来自Cassandra的答案：

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'}

但是当我执行此查询时：

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，你有什么建议吗？
