IMPALA-13844: Add /stacks web page to dump native thread stacks
Kudu 1.7 introduced a utility (KUDU-2291) and a /stacks web page
for dumping stack traces of all native threads. Impala already
has the corresponding debug util ported from Kudu, so this patch
adds a similar /stacks endpoint to Impala’s WebUI.
This enables developers to easily inspect thread states and
diagnose deadlocks or hangs via the web interface.
Testing:
Added unit tests to verify that the /stacks endpoint
is available and returns valid thread stack information.
TODO:
Add jstack output to the /stacks handler via a parameter like
`/stacks?include_jvm=true`. Note that `JniUtil.java` currently uses
`ThreadMXBean.dumpAllThreads()`, but Java’s `ThreadInfo` does not
expose native thread IDs (nids), limiting correlation with
native stacks.
