java.sql.SQLNonTransientConnectionException：org.apache.thrift.transport.TTransportException：幀大小大於最大長度（16384000）！

Question

我在具有Cassandra DB的IntellyJ中有一個Java項目，正在使用Maven 3和Java7。Cassandra版本為2.0.6。 我有一張近100,000行的表。 當我運行程序時，出現以下異常：

 java.sql.SQLNonTransientConnectionException: org.apache.thrift.transport.TTransportException: Frame size (16858796) larger than max length (16384000)!

我已經在Java 6的Eclipse中使用cassandra 1.2.8，一切正常！

PS：我在cassandra.yaml中將native_transport_max_frame_size_in_mb設置為256至512，將thrift_framed_transport_size_in_mb設置為15至32，但它沒有解決。

有身體可以幫助嗎？

Answer 1

請使用0.9.0版的Thrift。

Answer 2

將cassandra.yaml中的屬性start_native_transport更改為

start_native_transport: true

然后嘗試確保使用正確的端口進行操作。

您正在使用哪個API與Cassandra進行交互？
