-----------------------------------
Summary: 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: 0.94.14
Reporter: Dave Latham
Priority: Minor
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.
