---------------------------------------------------------------------------------------------------------
Key: HDFS-1949
URL: https://issues.apache.org/jira/browse/HDFS-1949
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.21.0, 0.20-append, 0.23.0
Reporter: ramkrishna.s.vasudevan
Priority: Minor
Fix For: 0.20.3
In the Namenode UI we have a text box to enter the chunk size.
The expected value for the chunk size is a valid Integer value.
If any invalid value, string or empty spaces are provided it throws number
format exception.
The existing behaviour is like we need to consider the default value if no
value is specified.
Soln
====
We can handle numberformat exception and assign default value if invalid value
is specified.
