I keep all my env variables in ~/.profile file, so they get exported when I open new shell. Recently I had to modify one of PATH parts, to downgrade from Hadoop 2.6.0 to Hadoop 2.3.0. So, my .profile looks like that (i commented out old HADOOP_INSTALL):
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 export GRADLE_HOME=/home/kranach/tools/gradle-2.2.1 #export HADOOP_INSTALL=/home/kranach/hadoop-2.6.0 export HADOOP_INSTALL=/home/kranach/hadoop-2.3.0 export M2_HOME=/home/kranach/tools/apache-maven-3.2.5 export PIG_HOME=/home/kranach/tools/pig-0.14.0 #export HIVE_HOME=/home/kranach/tools/apache-hive-0.14.0-bin/ export HIVE_HOME=/home/kranach/tools/hive12 export HBASE_HOME=/home/kranach/tools/hbase-0.98.10-hadoop2 PATH="$PATH:$GRADLE_HOME/bin:$HADOOP_INSTALL/bin:$HADOOP_INSTALL/sbin:$M2_HOME/bin:$PIG_HOME/bin:$HIVE_HOME/bin:$HBASE_HOME/bin"
After doing this change, I closed and re-opened terminal but without any effect - the PATH still contains hadoop 2.6.0 entry. I tried doing
source ~/.profile, but it only appends new entries to PATH, without replacing old one. What should I do to make changes to PATH visible then, without having to close all my windows and re-logging?
