Subject [jira] [Reopened] (HADOOP-8924) Hadoop Common creating package-info.java must not depend on sh
Date Tue, 04 Dec 2012 20:50:58 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8924?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Foley reopened HADOOP-8924:
--------------------------------


After discussion in common-dev@, the community consensus rejected use of Python. (see references
in HADOOP-9082)  Also, it was encouraged to take functionality out of scripts and move it
into core code.

I suggest that we convert saveVersion.sh to Java, and change the ant script to a recursive
call that compiles the java class and then invokes it.  Same thing should work in trunk, but
be aware there are two instances of saveVersion.sh in trunk: hadoop-common-project/hadoop-common/dev-support/saveVersion.sh
and hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/scripts/saveVersion.sh.  They are slightly
different, but I suspect that can and should be subsumed.

> Currently, the build process relies on saveVersion.sh to generate package-info.java with
a version annotation.  The sh binary may not be available on all developers' machines (e.g.
Windows without Cygwin). This issue tracks removal of that dependency in Hadoop Common.
