Question

每当查询特定表中的任何内容时，我都会收到错误消息“ ServerError：java.lang.IllegalArgumentException：null”。

我尝试过的示例查询：

select * from audit;
select * from audit limit 2;
select SPECIFIC_COLUMN from audit WHERE ID = '123456' ALLOW FILTERING;

存在数据：

nodetool cfstats -- keyspace_name.audit
Total number of tables: 55
----------------
Keyspace : keyspace_name
    Read Count: 0
    Read Latency: NaN ms
    Write Count: 0
    Write Latency: NaN ms
    Pending Flushes: 0
        Table: audit
        SSTable count: 2
        Space used (live): 99745
        Space used (total): 99745
        Space used by snapshots (total): 0
        Off heap memory used (total): 1456
        SSTable Compression Ratio: 0.2623552456457625
        Number of partitions (estimate): 900
        Memtable cell count: 0
        Memtable data size: 0
        Memtable off heap memory used: 0
        Memtable switch count: 0
        Local read count: 0
        Local read latency: NaN ms
        Local write count: 0
        Local write latency: NaN ms
        Pending flushes: 0
        Percent repaired: 100.0
        Bloom filter false positives: 0
        Bloom filter false ratio: 0.00000
        Bloom filter space used: 1160

使用sstabledump进行转储时，没有任何明显的变化：

sstabledump /opt/company/data/cassandra/data/keyspace_name/audit-501e5910887811e98345e1aa09bd5db5/mc-1-big-Data.db > test_dump

运行查询时来自：

/ var / log / messages中没有内容。

/var/log/cassandra/cassandra.log在启动时不存在。

nodetool修复，nodetool修复--trace entpor_access审核（修复中没有问题，它成功完成，重新启动节点，它存在于所有副本中，没有可用的备份，并且不确定如何恢复。

我非常确定IllegalArgumentException意味着您没有正确编写函数调用，或者忘记了在函数调用中指定参数。尽管我在Java领域没有特别的经验，但请查看Cassandra的文档，看看是否在代码中缺少参数。

在Cassandra中查询表时“ ServerError：java.lang.IllegalArgumentException：null”？
