Subject [jira] Created: (HADOOP-6388) Hadoop uses invalid names for environment variables
Date Tue, 24 Nov 2009 15:29:39 GMT
Hadoop uses invalid names for environment variables

                 Key: HADOOP-6388
                 URL: https://issues.apache.org/jira/browse/HADOOP-6388
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.20.1
            Reporter: Simone Leo

Variable names cannot contain dots and this is enforced starting from bash 4.0, see [http://www.mail-archive.com/bug-bash@gnu.org/msg05726.html].

An example of Hadoop functionality that breaks after upgrading to bash 4.0 is running Pipes
applications: the "hadoop.pipes.command.port" var is not passed and applications crash with
"Hadoop Pipes Exception: Illegal text protocol command".
