我正在使用Confluent JDBC-Source connector运行以下作业

代码语言:javascript
复制
{
    "name": "jobName",
    "config": {
        "connector.class": "io.confluent.connect.jdbc.JdbcSourceConnector",
        "mode": "timestamp",
        "timestamp.column.name": "dateColumn",
        "topic.prefix": "connect-test.",
        "connection.password": "pw",
        "tasks.max": "1",
        "connection.user": "un",
        "poll.interval.ms": "300000",
        "name": "jobName",
        "connection.url": "jdbc:sqlserver://serverName;Database=dbName;user=un;password=pw",
        "table.whitelist": "tableName"
    }
}

我有一个类似的Kafka-Connect作业在相同的数据库和相同的用户上成功运行,但使用另一个较小的表。所以连接不是问题所在。

在运行作业的Kafka-connect服务器上的日志中,我看到了以下内容:

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "pool-1-thread-4"

所以,没有太多可以继续下去的。运行此作业的服务器现在没有响应,并且不响应REST调用。有什么想法吗?
