Question

我的配置

具有两个节点的群集：

节点1：硬件：Intel Xeon 2.83 GHz（4核），24GB RAM，Dell VIRTUAL DISK SCSI 500GB
系统：Windows Server 2008 R2 x64
Java版本：7更新4 x64
Apache Cassandra版本：1.1.1
节点2：硬件：Intel Xeon 2.83 GHz（4核），8GB RAM，Dell VIRTUAL DISK SCSI 500GB
系统：Windows Server 2008 R2 x64
Java版本：7更新4 x64
Apache Cassandra版本：1.1.1

Cassandra服务器配置：

heap size: 4 GB
seed_provider:
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
      parameters:
         - seeds: "xxx.xxx.xxx.10,xxx.xxx.xxx.11"
listen_address: xxx.xxx.xxx.10
rpc_address: 0.0.0.0
rpc_port: 9160
rpc_timeout_in_ms: 20000
endpoint_snitch: PropertyFileSnitch

cassandra-topology.properties

xxx.xxx.xxx.10=datacenter1:rack1
xxx.xxx.xxx.11=datacenter1:rack1
default=datacenter1:rack1

问题

我已使用CLI命令处理了键空间和列族：

create keyspace testks with placement_strategy = 'org.apache.cassandra.locator.NetworkTopologyStrategy' and strategy_options = {datacenter1:2};
use testks;
create column family testcf;

然后我启动了我的Java应用程序，它使用Hector客户端插入了50 000 000行来创建列族。客户端连接到节点1。大约30秒后（插入160,000行）节点1上的Cassandra服务器抛出异常：

ERROR [COMMIT-LOG-ALLOCATOR] 2012-06-13 10:26:38,393 AbstractCassandraDaemon.java (line 134) Exception in thread Thread[COMMIT-LOG-ALLOCATOR,5,main]

    at org.apache.cassandra.db.commitlog.CommitLogSegment.<init>(CommitLogSegment.java:105)
    ... 5 more

然后，几秒钟后，节点2上的Cassandra服务器抛出相同的异常：

ERROR [COMMIT-LOG-ALLOCATOR] 2012-06-14 10:26:44,005 AbstractCassandraDaemon.java (line 134) Exception in thread Thread[COMMIT-LOG-ALLOCATOR,5,main]

    ... 5 more

之后，我的应用程序无法再插入任何数据。 Hector从Thrift获取TimedOutException：

我该如何解决？也许我做错了什么？

此致，Patrycjusz

Answer 1

Apache Cassandra并不完全支持Java 7。 http://www.datastax.com/docs/1.1/install/install_rpm

Java7不是“推荐”

正如您所发现的那样，使用1.6，您没有任何问题......
