Hadoop DFS is started and working, and I have changed /usr/local/hive/conf/hive-env.sh to export HADOOP_HOME.
Does anyone know what else can I do? Thanks.
回答1:
Apart from editing hive-env.sh, you also need to edit your bash_profile.
vim ~/.bash_profile
Add the following lines to your bash_profile
export HIVE_HOME=/usr/local/hive
export PATH=$PATH:$HIVE_HOME/bin
Save this file and then
source ~/.bash_profile
If this still doesnt work, please include your hive-env.sh file and hive-site.xml file. Also please tell me if you are using derby or mysql as metastore.

Solved moving:
export HADOOP_CLASSPATH=/usr/local/hbase/hbase-0.94.1.jar:/usr/local/hbase/hbase-0.94.1-test.jar:/usr/local/hbase/conf:/usr/local/hbase/lib/zookeeper-3.4.3.jar:/usr/local/hive/lib/*.jar:/usr/local/hbase
From /usr/local/hadoop/conf/hadoop-env.sh to ~/.bashrc
Thanks for the help.
