Simple question but reading through documentation and configuration I can’t quite seem to figure it out.
How do I A) know where hadoop is writing to on the local disk and B) change that
For initial testing I setup HDFS on a 20gb linux VM – to it we’ve added a 500gb networked drive for moving towards prototyping the full system. So now how do I point HDFS at that drive, or do I simply move the home directory/install with some slight change in setup and restart the process?
hadoop.tmp.dirholds the default directories.See the default core-default docs.
You can change the
core-site.xmlfile to set it (you could probably change it other places as well; that’s just where I happen to do it–I don’t know if it’s the “best” place to set that or not).
