-------------------------------------
Hi Alan,
Good point. In Bigtop, where we create RPM and DEB packages for hadoop and
bundle it into our Bigtop distribution, we do rely on this property.
And, looking at the code, it looks like we set that to be a user (hdfs user in
our case).
Here are the references:
These get used in the scripts we deploy using puppet for our integration
testing:
https://github.com/apache/bigtop/blob/master/bigtop-deploy/puppet/modules/hadoop/templates/hadoop-env.sh#L78
https://github.com/apache/bigtop/blob/master/bigtop-deploy/puppet/modules/hadoop/templates/hadoop-hdfs#L20
This gets used in the default configuration for our secure clusters for
integration testing:
https://github.com/apache/bigtop/blob/master/bigtop-packages/src/common/hadoop/conf.secure/hadoop-env.sh#L56
This gets used in the init script that starts the datanode services:
https://github.com/apache/bigtop/blob/master/bigtop-packages/src/common/hadoop/hadoop-hdfs-datanode.svc#L39
And, this gets used to set certain environment variables before starting
various HDFS services:
https://github.com/apache/bigtop/blob/master/bigtop-packages/src/common/hadoop/hdfs.default#L20
Hope that helps but please let me know if you need any further info.
