From: Andy Liu To: hadoop-user@lucene.apache.org Content-Type: multipart/alternative; boundary=00163646d5a01d1d3a0472200b66 X-Virus-Checked: Checked by ClamAV on apache.org --00163646d5a01d1d3a0472200b66 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit I'm running a test Hadoop cluster, which had a dfs.replication value of 3. I'm now running out of disk space, so I've reduced dfs.replication to 1 and restarted my datanodes. Is there a way to free up the over-replicated blocks, or does this happen automatically at some point? Thanks, Andy --00163646d5a01d1d3a0472200b66--
