Dinesh Chitlangia commented on HDFS-14182:
------------------------------------------
[~fengchuang] - Thank you for adding this improvement. Overall the patch LGTM.
+1 (non binding).
Minor suggestion:
You could avoid creating the local infoAddr variable as it is not being used
except in the following line.
{code:java}
if (index > x0 && index <= x1) {
var infoAddr = dn.infoAddr;
ips.push(infoAddr.split(":")[0]);
}
{code}
You could do something like:
{code:java}
if (index > x0 && index <= x1) {
ips.push(dn.infoAddr.split(":")[0]);
}
{code}
> Datanode usage histogram is clicked to show ip list
