[PR] YARN: escape the AM-supplied tracking url in the apps table blocks [hadoop]
nishat-06 opened a new pull request, #8617:
URL: https://github.com/apache/hadoop/pull/8617
### Description of PR
The apps tables in the RM, ApplicationHistory, FairScheduler and Router web UIs build their rows into a `StringBuilder` and emit the result inside a `<script>` element as `var appsTableData=...`. Every application-supplied column in that array (user, name, type, tags, queue) already goes through `escapeEcmaScript(escapeHtml4(...))`, but the tracking URL is concatenated straight into `href='...'`, and `ApplicationReport.getTrackingUrl()` hands back `RMAppAttemptImpl.originalTrackingUrl` verbatim for an unmanaged AM, so the string a client passes to `registerApplicationMaster` reaches the page unfiltered. A tracking URL holding a quote or a `</script>` closes the attribute or the script element and runs in the browser of anyone listing applications, so the escaping the neighbouring columns already use is applied here too. The Router copy has an `escape()` helper of its own that this one call site was skipping.
### How was this patch tested?
New `TestAppsBlock#testTrackingUrlIsEscaped` renders `AppsBlock` with a report whose tracking URL carries a `</script><script>` payload; it fails on trunk and passes with the change. `TestAppsBlock`, `TestRMWebApp`, `TestRMWebAppFairScheduler`, `TestAppPage` and `TestFederationWebApp` all pass, and checkstyle reports nothing new on the touched files.

The Yetus -1 is TestRouterWebServicesREST#testGetAppsMultiThread failing on a container-count assertion (expected 1 but was 0). That one spins up the mini-cluster and hits the REST endpoints; this change only escapes the tracking URL string in the web UI AppsBlock render path, so it doesn't touch that code. Looks like the usual flakiness in that multi-thread test rather than anything from the patch. Happy to retrigger or rebase if that helps.

Rebased onto latest trunk to kick off a fresh CI run, since that router REST failure looked like flakiness rather than anything from this change.
