Constructor Details

ExecuteProceduresRemoteCall

public ExecuteProceduresRemoteCall(ServerName serverName,
 Set<RemoteProcedureDispatcher.RemoteProcedure> remoteProcedures)

Method Details

getRsAdmin

private AsyncRegionServerAdmin getRsAdmin()
                                   throws IOException

Throws:

IOException

getServerName

protected final ServerName getServerName()

scheduleForRetry

private boolean scheduleForRetry(IOException e)

unableToConnectToServer

private boolean unableToConnectToServer(IOException e)

The category of exceptions where we can ensure that the request has not yet been received and/or processed by the target regionserver yet and hence we can determine whether it is safe to choose different regionserver as the target.

Parameters:

e - IOException thrown by the underlying rpc framework.

Returns:

true if the exception belongs to the category where the regionserver has not yet received the request yet.

isSaslError
