dfsadmin -setBalancerBandwidth doesnot validate -ve value
---------------------------------------------------------
Key: HDFS-2390
URL: https://issues.apache.org/jira/browse/HDFS-2390
Project: Hadoop HDFS
Issue Type: Bug
Components: balancer
Affects Versions: 0.20.205.0
Reporter: Rajit Saha
$ hadoop dfsadmin -setBalancerBandwidth -10000
does not throw any message that it is invalid although in DN log we are not
getting
"DNA_BALANCERBANDWIDTHUPDATE".
I think it should throw some message that -ve numbers are not valid , as it does
for decimal numbers or non-numbers like -
$ hadoop dfsadmin -setBalancerBandwidth 12.34
NumberFormatException: For input string: "12.34"
Usage: java DFSAdmin [-setBalancerBandwidth <bandwidth in bytes per second>]
