A Configuration instance cannot be reloaded if the configuration has
InputStream resources
------------------------------------------------------------------------------------------
Key: HADOOP-5000
URL: https://issues.apache.org/jira/browse/HADOOP-5000
Project: Hadoop Core
Issue Type: Bug
Environment: all
Reporter: Alejandro Abdelnur
If a {{Configuration}} instance as a stream resource, on an reload of
configuration values, the {{loadResource}} method will fail because the stream
has been already read in the first {{loadResource}} invocation.
For example:
{code}
InputStream is = ....
Configuration conf = new Configuration();
conf.addResource(is);
conf.set("a", "A");
conf.reloadConfiguration();
conf.set("a","B");
{code}
This example will fail on {{conf.set("b", "B");}} because it a
{{loadResources()}} will be done and the {{InputStream}} has been already
consumed.
