Steve Loughran commented on HADOOP-12969: ----------------------------------------- IPC client is used in YARN apps as it gives you kerberos IPC; You can't do REST to a YARN app as the RM proxy gets in the way. So it's Hadoop RPC or roll your own non-kerberized IPC mechanism. > Mark IPC.Client and IPC.Server as @Public, @Evolving > ---------------------------------------------------- > > Key: HADOOP-12969 > URL: https://issues.apache.org/jira/browse/HADOOP-12969 > Project: Hadoop Common > Issue Type: Improvement > Components: ipc > Affects Versions: 2.8.0 > Reporter: Xiaobing Zhou > Assignee: Xiaobing Zhou > Priority: Minor > > Per the discussion in > [HADOOP-12909|https://issues.apache.org/jira/browse/HADOOP-12909?focusedCommentId=15211745&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15211745], > this is to propose marking IPC.Client and IPC.Server as @Public, @Evolving > as a result of HADOOP-12909 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
