Question

我正在使用Spark Streaming下载网页并插入Hbase。我遇到以下异常：

WARN scheduler.TaskSetManager: Lost task 13.1 in stage 21.0 (TID 121,test1.server): java.lang.IllegalArgumentException: KeyValue size too large

我尝试增加hbase.client.keyvalue.maxsize，并设置hbase.client.keyvalue.maxsize = 0表示没有限制。另外，我增加了hdfs.blocksize = 256M。但是当我重新启动集群时，我仍然遇到同样的错误：keyvalue to large。请提出任何想法，提前谢谢！

Answer 1

hbase.client.keyvalue.maxsize是客户端属性。您需要在客户机节点上的hbase-site.xml中设置此属性。或者，您可以在Configuration对象的代码中设置此属性。无需为该属性重新启动HBase。

Hbase KeyValue的大小太大
