Chris Nauroth updated HADOOP-10840: ----------------------------------- Target Version/s: 3.0.0 (was: 3.0.0, 2.6.0) > Fix OutOfMemoryError caused by metrics system in Azure File System > ------------------------------------------------------------------ > > Key: HADOOP-10840 > URL: https://issues.apache.org/jira/browse/HADOOP-10840 > Project: Hadoop Common > Issue Type: Bug > Components: metrics > Affects Versions: 2.4.1 > Reporter: shanyu zhao > Assignee: shanyu zhao > Attachments: HADOOP-10840.patch > > > In Hadoop 2.x the Hadoop File System framework changed and no cache is > implemented (refer to HADOOP-6356). This means for every WASB access, a new > NativeAzureFileSystem is created, along which a Metrics source created and > added to MetricsSystemImpl. Over time the sources accumulated, eating memory > and causing Java OutOfMemoryError. > The fix is to utilize the unregisterSource() method added to MetricsSystem in > HADOOP-10839. -- This message was sent by Atlassian JIRA (v6.2#6252)
