Sushanth Sowmyan commented on HIVE-11149: ----------------------------------------- As an update, I do not think that we should be backporting HIVE-11891, since it refactors PerfLogger from hive-exec to hive-common, which is a cross-jar change that I don't think we should make on backport maint lines. However, this patch is simple enough that we could create a 1.2 version of this patch as well which will affect PerfLogger in hive-exec as it used to be in 1.2. > Fix issue with sometimes HashMap in PerfLogger.java hangs > ---------------------------------------------------------- > > Key: HIVE-11149 > URL: https://issues.apache.org/jira/browse/HIVE-11149 > Project: Hive > Issue Type: Bug > Components: Logging > Affects Versions: 1.2.1 > Reporter: WangMeng > Assignee: WangMeng > Fix For: 2.0.0 > > Attachments: HIVE-11149.01.patch, HIVE-11149.02.patch, > HIVE-11149.03.patch, HIVE-11149.04.patch > > > In Multi-thread environment, sometimes the HashMap in PerfLogger.java > will casue massive Java Processes hang and cost large amounts of > unnecessary CPU and Memory. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
