Key: HADOOP-561
URL: http://issues.apache.org/jira/browse/HADOOP-561
Project: Hadoop
Issue Type: Bug
Components: dfs
Reporter: Yoram Arnon
one replica of a file should be written locally if possible. That's currently
not the case.
Copying a 1GB file using hadoop dfs -cp running on one of the cluster nodes,
all the blocks were written to remote nodes, as seen by fsck -files -blocks
-locations on the newly created file.
as long as there is sufficient space locally, a local copy has significant
performance benefits.
