Configuration should trim property names and accept decimal, hexadecimal, and
octal numbers
-------------------------------------------------------------------------------------------
Key: HADOOP-2461
URL: https://issues.apache.org/jira/browse/HADOOP-2461
Project: Hadoop
Issue Type: Improvement
Components: conf
Reporter: Tsz Wo (Nicholas), SZE
Priority: Minor
I suggest two improvements in reading configuration:
- Suppose we have the following property in a conf file.
{code}
<property>
<name>
testing.property</name>
<value>something</value>
</property>
{code}
Try to get it by
{code}
Configuration conf = new Configuration();
String value = conf.get("testing.property"); //value == null here
{code}
We will get null since there is an eol in
{code}
<name>
testing.property</name>
{code}
I suggest to trim all property names.
- I also suggest configuration to accept decimal, hexadecimal, and octal
numbers (e.g. 011 is 9, 0xA is 10)
It can be easily done by replacing Integer.parseInt(...) with
Integer.decode(...) in Configuration.getInt(...), similarly, in
Configuration.getLong(...).
