问题
I successfully installed Hadoop 2.8.1 on Windows 10. Now I'm trying to install Hive version 2.1. When I try to start hive I receive the following error:
I have HADOOP_HOME set to D:\Hadoop-2.8.1\bin in the environment variables and added to the path system variable. Do I have to specify this path in a hive file?
回答1:
J Skinner,
You have wrongly set HADOOP_HOME.
In User variables, configure HADOOP_HOME with following value.
HADOOP_HOME-->D:\Hadoop-2.8.1
In System variables, add following value in addition of existing path value.
path--><Existing path values>;D:\Hadoop-2.8.1\bin;
If you not ok with that above configurations just try below way.
Open cmd prompt, Just set home by setting path and home.
C:>set HADOOP_HOME=D:\Hadoop-2.8.1
C:>set PATH=%PATH%;%HADOOP_HOME%\bin
Now start hadoop services from same cmd prompt and then go to hive shell.
Hope this helpful for you.
