Hbase KeyValue 大小太大

Question

我正在使用 Spark Streaming 下载网页并插入到 Hbase 中。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

我试过增加hbase.client.keyvalue.maxsize，设置hbase.client.keyvalue.maxsize=0表示没有限制。此外，我增加了 hdfs.blocksize=256M。但是当我重启集群的时候，还是遇到同样的错误:keyvalue to large。请有任何想法，提前致谢!

hbase.client.keyvalue.maxsize 是客户端属性。您需要在客户端节点上的 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。
