/1, /2 is not actually an attempt id, so how to convert this to an valid
attempt id?
In the code of history server:
```scala
private val loaderServlet = new HttpServlet {
protected override def doGet(req: HttpServletRequest, res:
HttpServletResponse): Unit = {
// Parse the URI created by getAttemptURI(). It contains an app ID
and an optional
// attempt ID (separated by a slash).
val parts = Option(req.getPathInfo()).getOrElse("").split("/")
if (parts.length < 2) {
res.sendError(HttpServletResponse.SC_BAD_REQUEST,
s"Unexpected path info in request (URI = ${req.getRequestURI()}")
return
}
val appId = parts(1)
val attemptId = if (parts.length >= 3) Some(parts(2)) else None
```
The GET url will be split into two fields, `appId` and `attemptId`, so if
the URL you mentioned is accessible, `attemptId` will be 1 or 2, am not sure
how to use this to get the right event log?
