Allen Wittenauer updated HADOOP-10787:
--------------------------------------
Release Note:
<!-- markdown -->
The following shell environment variables have been deprecated:
| Old | New |
|:---- |:---- |
| DEFAULT_LIBEXEC_DIR | HADOOP_DEFAULT_LIBEXEC_DIR |
| SLAVE_NAMES | HADOOP_SLAVE_NAMES |
| TOOL_PATH | HADOOP_TOOLS_PATH |
In addition:
* DEFAULT_LIBEXEC_DIR will NOT be automatically transitioned to
HADOOP_DEFAULT_LIBEXEC_DIR and will require changes to any scripts setting that
value. A warning will be printed to the screen if DEFAULT_LIBEXEC_DIR has been
configured.
* HADOOP_TOOLS_PATH is now properly handled as a multi-valued, Java
classpath-style variable. Prior, multiple values assigned to TOOL_PATH would
not work a predictable manner.
> Rename/remove non-HADOOP_*, etc from the shell scripts
