Hive + Hbase,

Hive + Hbase,


在hive-site.xml里面有两个配置选项,配置好后可以应用hive执行到hbase集群

hive.aux.jars.path
file:///app/java/hive/lib/hive-hbase-handler-0.7.1.jar,file:///app/java/hive/lib/hbase-0.90.3.jar,file:///app/java/hive/lib/zookeeper-3.3.1.jar



hbase.zookeeper.quorum
dfsname1.cptrue.com
The directory shared by region servers.



Currently, we allocated mapred.child.java.opts = -Xmx455037693, we need to increase to 1G. That would be tuning number 1.

we need to increase the usage of mapred.job.reuse.jvm.num.tasks to -1. So every maps/reducers will reuse JVM instead of spanning the new ones.

用mapreduce jobtracker查看hive执行情况
