Hi :) In the current hadoop-common trunk, bin/start-all.sh has been deprecated. In order to start the cluster, we have to go to hadoop-hdfs trunk and hadoop-mapred trunk and run bin/start-dfs.sh and bin/start-mapred, separately. However, when I do so, I always get the error message "can't find hadoop common". This problem can be solved if I export HADOOP_COMMON_HOME to be hadoop-common trunk, but is there a way to configure this environment variable so that I don't have to export HADOOP_COMMON_HOME every time when I start the cluster?
Please help me if possible? Thank you very much! -Rita :))
