Hi, All,
Checked again that when I hover cursor on the stdout/stderr, it points to
links of IP address of the master node, so that's why when clicking on it
nothing will show up. While the "Download" button beside it points
correctly to the IP address of slave node, so I can download them without
problem. Seems a config problem somewhere? A bit lost here.
So seems the "host" in the pailer function is resolved to master instead of
slave node:
14 // Invokes the pailer for the specified host and path using the
15 // specified window_title.
16 function pailer(host, path, window_title) {
17 var url = 'http://' + host + '/files/read.json?path=' + path;
18 var pailer =
19 window.open('/static/pailer.html', url, 'width=580px,
height=700px');
20
21 // Need to use window.onload instead of document.ready to make
22 // sure the title doesn't get overwritten.
23 pailer.onload = function() {
24 pailer.document.title = window_title + ' (' + host + ')';
25 };
26 }
27
Cheers,
Dan
