Hi, in hdfs-site.xml:
<property> <name>dfs.datanode.du.reserved</name> <value> VALUE_HERE (maybe 30000000000) </value> </property> <property> <name>dfs.datanode.du.pct</name> <value>0.9f</value> </property> But not available for each partition, its a general parameter. Correct me please if I wrong. regards, Alex On Thu, Oct 27, 2011 at 2:24 AM, Rita <[email protected]> wrote: > What is the correct way to reserve space for hdfs? > > I currently have 2 filesystem, /fs1 and /fs2 and I would like to reserve > space for non-dfs operations.
