Dear All, I have few questions on "dfs.datanode.du.reserved" property in hadoop-site.xml configuration...
Assuming that I have "dfs.datanode.du.reserved = 10GB" and the partition assigned for HDFS has already been filled up to its capacity. (In this case, it will be Total disk size minus 10GB) What happens if I change "dfs.datanode.du.reserved" value to something greater than 10GB, like 20GB? Will HDFS remove or move blocks to meet that settings? Also, is it possible to set that "dfs.datanode.du.reserved" separately on each partition? (e.g. reserve 30GB for /data1 partition, reserve 100GB for /data2 partition) Many thanks, Taeho
