Ted Yu commented on HBASE-10089: -------------------------------- Integrated to 0.94 Thanks for the verification, Jean-Marc. Thanks for the reviews. > Metrics intern table names cause eventual permgen OOM in 0.94 > ------------------------------------------------------------- > > Key: HBASE-10089 > URL: https://issues.apache.org/jira/browse/HBASE-10089 > Project: HBase > Issue Type: Bug > Affects Versions: 0.94.0, 0.94.14 > Reporter: Dave Latham > Assignee: Ted Yu > Priority: Minor > Fix For: 0.94.15 > > Attachments: 10089-0.94.txt > > > As part of the metrics system introduced in HBASE-4768 there are two places > that hbase uses String interning ( SchemaConfigured and SchemaMetrics ). > This includes interning table names. We have long running environment where > we run regular integration tests on our application using hbase. Those tests > create and drop tables with new names regularly. These leads to filling up > the permgen with interned table names. Workaround is to periodically restart > the region servers. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
