[jira] Created: (HADOOP-7121) Exceptions while serializing IPC call
response are not handled well
Exceptions while serializing IPC call response are not handled well
-------------------------------------------------------------------
Key: HADOOP-7121
URL: https://issues.apache.org/jira/browse/HADOOP-7121
Project: Hadoop Common
Issue Type: Bug
Components: ipc
Affects Versions: 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
Fix For: 0.22.0
We had a situation where for some reason the serialization of an RPC call's response was throwing OOME. When this happens, the exception is not caught, and the call never gets a response - the client just hangs. Additionally, the OOME propagated all the way to the top of the IPC handler and caused the handler. Plus, the Handler upon exit only logged to stdout and not to the log4j logs.

--------------------------------
Attachment: hadoop-7121.txt
Attached patch adds coverage to all parts of the IPC lifecycle:
- client side write param
- server side read param
- server side write response
- client side read response
In the cases that the error occurs server side, it sends back the exception to the client as well as logging it.

> We had a situation where for some reason the serialization of an RPC call's response was throwing OOME. When this happens, the exception is not caught, and the call never gets a response - the client just hangs. Additionally, the OOME propagated all the way to the top of the IPC handler and caused the handler. Plus, the Handler upon exit only logged to stdout and not to the log4j logs.
