Hiroshi Ikeda commented on HBASE-14279: --------------------------------------- Sorry, these days ConcurrentHashMap seems much more sophisticated using UNSAFE... > Race condition in ConcurrentIndex > --------------------------------- > > Key: HBASE-14279 > URL: https://issues.apache.org/jira/browse/HBASE-14279 > Project: HBase > Issue Type: Bug > Reporter: Hiroshi Ikeda > Assignee: Heng Chen > Priority: Minor > Attachments: HBASE-14279.patch, HBASE-14279_v2.patch, > HBASE-14279_v3.patch, HBASE-14279_v4.patch, HBASE-14279_v5.patch, > LockStripedBag.java > > > {{ConcurrentIndex.put}} and {{remove}} are in race condition. It is possible > to remove a non-empty set, and to add a value to a removed set. Also > {{ConcurrentIndex.values}} is vague in sense that the returned set sometimes > trace the current state and sometimes doesn't. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
