Do not assign blocks to a datanode with < x mb free
---------------------------------------------------
Key: HADOOP-296
URL: http://issues.apache.org/jira/browse/HADOOP-296
Project: Hadoop
Type: New Feature
Components: dfs
Versions: 0.3.2
Reporter: Johan Oskarson
We're running a smallish cluster with very different machines, some with only
60 gb harddrives
This creates a problem when inserting files into the dfs, these machines run
out of space quickly and then they cannot run any map reduce operations
A solution would be to not assign any new blocks once the space is below a
certain user configurable threshold
This free space could then be used by the map reduce operations instead (if
that's on the same disk)
