ipc.client.connect.max.retries.on.timeouts default value is too many
Lisheng Sun created HADOOP-16553:
------------------------------------
Summary: ipc.client.connect.max.retries.on.timeouts default value is too many
Key: HADOOP-16553
URL: https://issues.apache.org/jira/browse/HADOOP-16553
Project: Hadoop Common
Issue Type: Improvement
Reporter: Lisheng Sun
Assignee: Lisheng Sun
Current ipc connection retry default times is 45 when socket timeout. Socket timeout default is 20s.
So if network packet loss on received machine，client need wait at most 15 mins.
I think ipc connection retry default times should decreate.
{code:java}
public static final String IPC_CLIENT_CONNECT_MAX_RETRIES_ON_SOCKET_TIMEOUTS_KEY =
"ipc.client.connect.max.retries.on.timeouts";
/** Default value for IPC_CLIENT_CONNECT_MAX_RETRIES_ON_SOCKET_TIMEOUTS_KEY */
public static final int IPC_CLIENT_CONNECT_MAX_RETRIES_ON_SOCKET_TIMEOUTS_DEFAULT = 45;
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}
