Subject Re: Installing both hadoop1 and haddop2 on single node
Date Mon, 05 May 2014 05:49:03 GMT
I think you need to set two different environment variables for hadoop1 and
hadoop2, such as HADOOP_HOME, HADOOP_CONF_DIR and before you run hadoop
command, you need to make sure the correct environment variables are enable.
