| ## This is where you can redefine the layout of Hadoop directories |
| ## and expect to be reasonably compatible. Needless to say, this |
| ## is expert level stuff and one needs to tread carefully. |
| ## |
| ## If you move HADOOP_LIBEXEC_DIR from some location that |
| ## isn't bin/../libexec, you MUST define either HADOOP_LIBEXEC_DIR |
| ## or have HADOOP_HOME/libexec/hadoop-config.sh and |
| ## HADOOP_HOME/libexec/hadoop-layout.sh (this file) exist. |
| |
| ## NOTE: |
| ## |
| ## hadoop-functions.sh gets executed BEFORE this file. So you can |
| ## redefine all of those functions here. |
| ## |
| ## *-env.sh get executed AFTER this file but generally too late to |
| ## override the settings (but not the functions!) here. However, this |
| ## also means you cannot use things like HADOOP_CONF_DIR for these |
| ## definitions. |
