---------------------------------
[~inigoiri] I have checked federationhealth.js, there is no seperate sync ajax
request likes in dfshealth.js.
{code:java}
$.ajax({'url': '/conf', 'dataType': 'xml', 'async': false}).done(
function(d) {
var $xml = $(d);
var namespace, nnId;
$xml.find('property').each(function(idx,v) {
if ($(v).find('name').text() === 'dfs.nameservice.id') {
namespace = $(v).find('value').text();
}
if ($(v).find('name').text() === 'dfs.ha.namenode.id') {
nnId = $(v).find('value').text();
}
});
if (namespace && nnId) {
data['HAInfo'] = {"Namespace": namespace, "NamenodeID": nnId};
}
});{code}
