Mohammad Kamrul Islam reassigned KNOX-989: ------------------------------------------ Assignee: Mohammad Kamrul Islam > Revisit JMX Metrics to fix the Out of Memory issue > -------------------------------------------------- > > Key: KNOX-989 > URL: https://issues.apache.org/jira/browse/KNOX-989 > Project: Apache Knox > Issue Type: Bug > Components: Server > Reporter: Sandeep More > Assignee: Mohammad Kamrul Islam > Fix For: 0.14.0 > > > Bug [KNOX-986|https://issues.apache.org/jira/browse/KNOX-986] uncovers > problem with Metrics when large number of unique URLs are accessed via Knox. > The problem here is that Knox creates metrics objects per unique URL, the > metrics objects are not flushed out (for obvious reason - to maintain the > metric state). > We need to come up with a proper fix to mitigate this while being able to use > the JMX Metrics. > One way of doing this would be to have Metrics objects at service level ( > e.g. /gateway/sandbox/webhdfs/* ) the other way would be to have a reaper > process that clears out the unused objects.
