[jira] [Commented] (HBASE-27486) HTable MetricsTableLatencies not remove trigger memory leak
[ https://issues.apache.org/jira/browse/HBASE-27486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17697973#comment-17697973 ] Bryan Beaudreault commented on HBASE-27486: --- This was resolved by HBASE-27681, but that can't be directly backported to 2.4.x or 2.5.x because it incompatible changes to metric names/organization. It will come with 2.6.0 when that's released. One could theoretically do a targeted backport of just the registry changes of that jira, without the renames.

When I delete a table, I can still see the latency data of the deleted table in the /jmx endpoint.I don't know whether the design is like this or the handling is omitted.I read source code of historical version and found that this problem always exists, so I marked 2.0.0. > HTable MetricsTableLatencies not remove trigger memory leak > > > Key: HBASE-27486 > URL: https://issues.apache.org/jira/browse/HBASE-27486 > Project: HBase > Issue Type: Bug > Components: metrics, regionserver >Affects Versions: 2.0.0 >Reporter: Moran >Priority: Major > > MetricsTableLatenciesImpl histogramsByTable only put but not remove.Maybe we > should remove it when table disabled. > supplement: > MetricsTableQueryMeterImpl metersByTable has the same problem. -- This message was sent by Atlassian Jira (v8.20.10#820010)

I'd suggest you try to write a unit test to demonstrate this happening if you plan to fix it. Related, if you're still using HBase 2.0, I think you have much larger problems as that has been EOL for quite some time. > HTable MetricsTableLatencies not remove trigger memory leak > > > Key: HBASE-27486 > URL: https://issues.apache.org/jira/browse/HBASE-27486 > Project: HBase > Issue Type: Bug > Components: metrics, regionserver >Affects Versions: 2.0.0 >Reporter: Moran >Priority: Major > > MetricsTableLatenciesImpl histogramsByTable only put but not remove.Maybe we > should remove it when table disabled. > supplement: > MetricsTableQueryMeterImpl metersByTable has the same problem. -- This message was sent by Atlassian Jira (v8.20.10#820010)
