Chris Nauroth updated HADOOP-11966:
-----------------------------------
Attachment: HADOOP-11966-branch-2.001.patch
The attached patch refactors setting the {{cygwin}} variable into
hadoop-config.sh, where it can take effect for all the interactive scripts as
well as hadoop-daemon.sh. This is more like how the branch-1 code handled it.
Unfortunately, I missed it the first time.
I have retested Cygwin/Windows with this change. I also retested
hadoop-daemon.sh on Linux.
> Variable cygwin is undefined in hadoop-config.sh when executed through
> hadoop-daemon.sh.

> HADOOP-11464 reinstated support for running the bash scripts through Cygwin.
> The logic involves setting a {{cygwin}} flag variable to indicate if the
> script is executing through Cygwin. The flag is set in all of the
> interactive scripts: {{hadoop}}, {{hdfs}}, {{yarn}} and {{mapred}}. The flag
> is not set through hadoop-daemon.sh though. This can cause an erroneous
> overwrite of {{HADOOP_HOME}} and {{JAVA_LIBRARY_PATH}} inside
> hadoop-config.sh.
