Omkar Vinit Joshi commented on YARN-1061:
-----------------------------------------
How can NM wait infinitely? I mean what is your connection timeout set to? can
you add below parameters to your log4j.properties and see if actually times out
or wait infinitely for RM... Also can attach those logs once you simulate it?
{code}
log4j.logger.org.apache.hadoop.ipc.Server=DEBUG
log4j.logger.org.apache.hadoop.ipc.Client=DEBUG
{code}
Also helpful configurations from *CommonConfigurationKeysPublic*
{code}
public static final String IPC_CLIENT_CONNECTION_MAXIDLETIME_KEY =
"ipc.client.connection.maxidletime";
/** Default value for IPC_CLIENT_CONNECTION_MAXIDLETIME_KEY */
public static final int IPC_CLIENT_CONNECTION_MAXIDLETIME_DEFAULT =
10000; // 10s
/** See <a href="{@docRoot}/../core-default.html">core-default.xml</a> */
public static final String IPC_CLIENT_CONNECT_TIMEOUT_KEY =
"ipc.client.connect.timeout";
/** Default value for IPC_CLIENT_CONNECT_TIMEOUT_KEY */
public static final int IPC_CLIENT_CONNECT_TIMEOUT_DEFAULT = 20000; // 20s
{code}
