hbase集群写不进去数据的问题追踪过程
日期：2015-06-08点击：715收藏
hbase从集群中有8台regionserver服务器，已稳定运行了5个多月，8月15号，发现集群中4个datanode进程死了，经查原因是内存 outofMemory了(因为这几台机器上部署了spark，给spark开的-Xmx是32g)，然后对从集群进行了恢复并进行了补数据，写负载比较 重，又运行了几天，发现从集群写不进去数据了
①、regionserver端

hadoop: hive 1.2.0 在mac机上的安装与配置
环境：mac OS X Yosemite + hadoop 2.6.0 + hive 1.2.0 +jdk 1.7.0_79 前提：hadoop必须先安装，且处于运行状态（伪分式模式或全分布模式均可） hive官网地址：http://hive.apache.org/ 建议：经个人实践，在mac OS X Yosemite 环境下，如果使用apache下载的原始hadoop 2.6.0，不管jdk安装成什么版本（1.6\1.7\1.8都试过），hive 1.2.0启动时，始终报jdk版本不匹配，后来在mac上将hadoop 2.6.0源编译成mac原生版本后，就正常了。 如果有朋友也遇到类似情况，请参考 mac OS X Yosemite 上编译hadoop 2.6.0/2.7.0及TEZ 0.5.2/0.7.0 注意事项 一、环境变量 ... export HADOOP_HOME=/home/hadoop/hadoop-2.6.0 export HIVE_HOME=/home/hadoop/hive-1.2.0 ... export HADOOP_CONF_DIR=${HADOOP_H...

Hbase写入量大导致region过大无法split问题
最近在线上往hbase导数据，因为hbase写入能力比较强，没有太在意写的问题。让业务方进行历史数据的导入操作，中间发现一个问题，写入速度太快，并且业务数据集中到其中一个region，这个region无法split掉，处于不可用状态。这里描述一整个过程—— 事情的起因：业务方按照userid和商品id作为rowkey前缀，并没有进行hash散列。我当时咨询过业务方，认为：1.业务方式按照oracle的rowid顺序来进行迁移的，相对来说对应到rowkey里面就不会集中化；2.即使出现部分集中的情况，hbase也能够通过自动split来hold住写入。 结果线上写入的时候，12台机器的情况下业务方写入达到50~60w tps，基本上5w tps每台的写入速度。开始的时候region还能够自动split，比较好，写入速度也能够保持，但是到了第二天，发现写入在region维度的分布很不均衡，于是查看表的region size 情况，有一个region数据量特别大——800GB，700+个文件。 这里也分析一下为什么hbase会让这么大的region存在，其实这块hbas...
