----------------------------------------
Summary: Ozone recon server possible memory leak
Key: HDDS-7500
URL: https://issues.apache.org/jira/browse/HDDS-7500
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Recon
Reporter: Devesh Kumar Singh
This seems to be an issue in Recon and needs fix after analysing the OM rocks
DB. In Recon, we are running a namespacesummary task and this task keeps
iterating all elements from directoryTable without considering the fact loading
all elements in memory and if elements are more in number, this may cause
OOM... After I checked the OM rocks DB of cluster, I can see millions of
directories and they all will be loaded in memory by NameSpaceSummary task for
FSO buckets to store and flush the data in NameSpaceSummaryTable of recon sql
DB. This needs fix.
