KUDU-3549 fix WriteAsPrometheus() for non-arithmetic gauges

This patch fixes WriteAsPrometheus() implementation for string-based
gauges.  The original changelist that introduced Prometheus metrics
had a proper implementation of WriteAsPrometheus() only for StringGauge,
but any FunctionGauge for a non-arithmetic type (e.g., for std::string)
would still output a string value in Prometheus text format, and that
could not be consumed by Prometheus.  The patch also contains a test
scenario that would fail without the fix.

This is a follow-up to 00efc6826ac9a1f5d10750296c7357790a041fec.

[jira] [Created] (KUDU-3551) Upgrade Gradle

2024-02-06 Thread Zoltan Chovan (Jira)

 Summary: Upgrade Gradle
 Key: KUDU-3551
 URL: https://issues.apache.org/jira/browse/KUDU-3551
 Project: Kudu
  Issue Type: Improvement
Reporter: Zoltan Chovan
Assignee: Zoltan Chovan


Since the Gradle version in Kudu is 6.8.2 (the project defines 6.9.2, but the 
wrapper is still at 6.8.2), which is roughly 3 years old, it's probably time to 
upgrade.

The maven plugin is deprecated, so the publishing/signing of artifacts needs to 
be reworked with maven-publish plugin.

Upgrading also would enable Kudu to be built with newer java versions.

[test] a small clean-up on StringGaugePrometheusTest

I took a quick look at KUDU-3549, and a natural first step was to check
whether we have a proper test coverage for handling StringGauge in when
dumping metrics in Prometheus format.  The result was this patch, adding
a couple new sub-scenarios into MetricsTest.StringGaugePrometheusTest.

While this didn't lead to discovering the root case of the reported
issue, the new sub-scenarios are still useful since they provide extra
coverage for the related functionality.  I also took the liberty of
cleaning up the code a bit.
