----------------------------------------
Summary: [NFS GW] IdleStateHandler is not Shareable
Key: HADOOP-18584
URL: https://issues.apache.org/jira/browse/HADOOP-18584
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.4.0
Reporter: Wei-Chiu Chuang
The ChannelHandler that can be added to a ChannelPipeline in Netty4 must be
Shareable. However, IdleStateHandler, used by Portmap is not.
We need to fix it otherwise hadoop portmap may fail to start.
This is a regression from HADOOP-11245 but I consider it not a blocker, because
most recent Linux distro supports rpcbind and there's little reason to use
Hadoop's portmap.
