Tsuyoshi OZAWA commented on HIVE-7409: -------------------------------------- [~xuefuz], Thanks for your comment. The issue is fixed on [JDK-7122142|https://bugs.openjdk.java.net/browse/JDK-7122142], but the issue has potential deadlock problem, which is described on [JDK-7031759|https://bugs.openjdk.java.net/browse/JDK-7031759], duplicated ticket of [JDK-7122142|https://bugs.openjdk.java.net/browse/JDK-7122142] - calling {{getAnnotations()}} from synchronized static method(e.g. {{isStateful}}) can cause deadlock on JDK7 and JDK8. Therefore, IMHO, we should fix it on Hive side. > Add workaround for a deadlock issue of Class.getAnnotation() > ------------------------------------------------------------- > > Key: HIVE-7409 > URL: https://issues.apache.org/jira/browse/HIVE-7409 > Project: Hive > Issue Type: Bug > Reporter: Tsuyoshi OZAWA > Attachments: HIVE-7409.1.patch > > > [JDK-7122142|https://bugs.openjdk.java.net/browse/JDK-7122142] mentions that > there is a race condition in getAnnotations. This problem can lead deadlock. > The fix on JDK will be merged on jdk8, but hive supports jdk6/jdk7 currently. > Therefore, we should add workaround to avoid the issue. -- This message was sent by Atlassian JIRA (v6.2#6252)
