Stephen Fritz created HDFS-4113:
-----------------------------------
Summary: When adding datanodes with less disk capacity to an
existing cluster, the new DNs fill up faster and subsequently cause errors
during put operations
Key: HDFS-4113
URL: https://issues.apache.org/jira/browse/HDFS-4113
Project: Hadoop HDFS
Issue Type: New Feature
Components: data-node
Reporter: Stephen Fritz
Priority: Minor
The request is that the allocation strategy be modified so that it allocates
equally on a 'free space percentage' basis between datanodes. IE disks that are
twice as big should have twice as much data written to them per unit time.
