Chris Nauroth commented on HADOOP-11485:
----------------------------------------
I think v03 has some issues with usage of {{hadoop_translate_cygwin_path}} in
shellprofile.d/yarn:
{code}
hadoop_translate_cygwin_path "${yld}"
{code}
Inside {{hadoop_translate_cygwin_path}}, the argument is part of an {{eval}}
for setting (possibly changing) the variable value, so instead of expanding the
variable's value at the call site, we just need to pass through the variable
name:
{code}
hadoop_translate_cygwin_path yld
{code}
Also, I think I see a typo, defining variable {{yhd}}, but then trying to use
{{ygd}}:
{code}
local yhd=$HADOOP_YARN_HOME
hadoop_translate_cygwin_path "${ygd}"
{code}

> It would be useful to provide a way for core and non-core Hadoop components
> to plug into the shell infrastructure. This would allow us to pull the HDFS,
> MapReduce, and YARN shell functions out of hadoop-functions.sh.
> Additionally, it should let 3rd parties such as HBase influence things like
> classpaths at runtime.
