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#6144)
