Subject [jira] Commented: (HADOOP-352) Portability of hadoop shell scripts for deployment
Date Fri, 07 Jul 2006 13:09:30 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-352?page=comments#action_12419705 ] 

Jean-Baptiste Quenot commented on HADOOP-352:

Yes, with my patch, the Hadoop scripts is deployed and runs on FreeBSD.

BTW I didn't mention in the previous comment, "if [ -a file ]" constructs are not compatible.

Installing bash on FreeBSD is straightforward provided that you symlink /bin/bash to /usr/local/bin/bash.
 But we must address Solaris deployment soon, and installing bash is more complicated.

> Hadoop shell scripts are based on /bin/bash, which is a "standard" shell only on GNU/Linux.
 On other Unix systems like FreeBSD however the "standard" shell is /bin/sh.  The attached
patch addresses these compatiblity issues.  Note that Solaris support is not yet tested.
> Also, the best way to set the HADOOP_HOME variable upon ssh connection in a portable
way is to set it in .ssh/environment.  The bash startup script ".bashrc" is not an option
on systems where "bash" is not installed.
