综上所述,当遇到“HBase waiting for actions to finish”时,不必过于担心,可以通过优化操作或增加资源来提高操作执行效率。使用 HBase 时,需要注意处理好可能出现的等待操作完成的情况,以保证系统正常运行。
1)写端抛出以下异常信息: org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException: Failed 150 actions: NotServingRegionException: 150 times, servers with issues: my161208.cm6:60020, at org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation.processBatchCallback(HConnectionMa...
引自:https://blog.csdn.net/xiefu5hh/article/details/53056113 问题:往hbase写入数据时一直报AsyncRequestFutureImpl: #5, waiting for 102733 actions to finish on table。之后报错RetriesExhaustedWithDetailsException,断开连接 原因:写入数据时,短时间内写入数据量过大导致写入异常。 解决方法:修改了写入hbase频...
线上程序在运行一段时间偶尔会报(AsyncRequestFutureImpl.java:1196)- #1, waiting for 148 actions to finish on table: monitor:entry_table 分析 首先我们是知道线上环境CDH的配置弱鸡,网络的带宽和稳定性也是一言难尽(网络经常有波动,带宽也小)。 结合hbase运行日志和图表初步认为报这个的原因是当hbase并发量...

You’ve covered a lot of ground in understanding HBase and how to build applications effectively. We also looked at how to deploy HBase clusters in a fully distributed fashion, what kind of hardware to choose, the various distribution options, and how to configure the cluster. All this infor...
Apache HBase [1] is an open-source, distributed, versioned, column-oriented store modeled after Google' Bigtable: A Distributed Storage System for Structured Data by Chang et al.[2] Just as Bigtable leverages the distributed data storage provided by the Google File System, HBase provides Big...
