Hudson commented on HBASE-19708: -------------------------------- SUCCESS: Integrated in Jenkins build HBase-1.2-IT #1054 (See [https://builds.apache.org/job/HBase-1.2-IT/1054/]) HBASE-19708 Avoid NPE when the RPC listener's accept channel is closed (apurtell: rev d48f9e4d40aacb2fb624c8cfd8ecbc83be5074fd) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/RpcServer.java > Avoid NPE when the RPC listener's accept channel is closed > ---------------------------------------------------------- > > Key: HBASE-19708 > URL: https://issues.apache.org/jira/browse/HBASE-19708 > Project: HBase > Issue Type: Bug > Affects Versions: 0.98.24 > Reporter: Andrew Purtell > Assignee: Andrew Purtell > Priority: Minor > Fix For: 1.3.2, 1.4.1, 1.5.0, 1.2.7 > > Attachments: HBASE-19708-branch-1.patch, HBASE-19708-branch-1.patch > > > Rare NPE when the listener's accept channel is closed. We serialize access to > related state to avoid a previously fixed related NPE and need to do the same > for {{acceptChannel}}. Seen in a 0.98 deploy but I think applicable to later > code lines.
