-----------------------------------------
Summary: MetricsStochasticBalancerSource metrics don't render in
/jmx endpoint
Key: HBASE-26745
URL: https://issues.apache.org/jira/browse/HBASE-26745
Project: HBase
Issue Type: Bug
Reporter: Bryan Beaudreault
The check in JSONBean
[here|https://github.com/apache/hbase/blob/master/hbase-http/src/main/java/org/apache/hadoop/hbase/util/JSONBean.java#L266]
causes the balancer cost metrics to be excluded from the jmx endpoint. I think
we should just remove the check for ":". I don't think including metrics with a
colon in them poses any problem, since the strings are quoted. We removed this
check in our cdh5 fork almost a year ago and have not seen any issues.
Alternatively we can fix the MetricsStochasticBalancerSource metrics to emit
metrics that adhere to these filters, but I think that would be a backwards
incompatible change since this is only a json rendering issue and people might
be consuming JMX directly.
