[jira] [Commented] (HADOOP-8055) Distribution tar.gz does not contain etc/hadoop/core-site.xml

Harsh J commented on HADOOP-8055:
---------------------------------

Noticed the same thing when playing with CDH4b1 assemblies of 0.23.x.

Thanks for reporting and filing a patch Eric!

The idea of the patch is right but the location is wrong. Based on assemblies from hadoop-assemblies, from what little I know of mvn, it seems we assemble the etc/hadoop bits from each projects' src/main/conf directory.

Sure enough, hadoop-common's src/main/conf is empty. We need the core-site.xml created there for an ideal fix, and it will get assembled. Could you refactor your patch to do this instead of using hdfs?

> A dist built from trunk (0.24.0-SNAPSHOT) does not contain a core-site.xml in $HADOOP_HOME/etc/hadoop/ folder.
> $HADOOP_HOME/sbin/start-dfs.sh without that folder gives an exception
> Exception in thread "main" java.lang.IllegalArgumentException: URI has an authority component
>  at java.io.File.<init>(File.java:368)

> Manually creating $HADOOP_HOME/etc/hadoop/core-site.xml solves this problem and hadoop starts fine.
