Method Detail

hasServiceType

boolean hasServiceType()

 The purpose of this field is to make grpc service on standby masters work without
 making client changes and keeps backwards compatibility.
 This requests to this endpoint will be rejected on standby masters by default,
 unless this field is set.
 Two places use this request:
 1. PollingMasterInquireClient uses this endpoint to tell who is the primary master.
 2. AbstractClient uses this endpoint to verify the version before it RPCs with the master.
 Behaviors:
 1. old clients -> new cluster standby masters
 PollingMasterInquireClient does not set this field and is able to tell which one is primary master because
 the request will be rejected on the standby master.
 AbstractClient does not set this field.
 Old clients only connects to primary so this doesn't break the existing behavior.
 2. new clients -> new cluster standby masters
 PollingMasterInquireClient does not set this field and is able to tell which one is primary master because
 the request will be rejected on the standby master.
 AbstractClient sets this field to true. Rpcs to standby masters can go through and pass the version verification.
 

optional .alluxio.grpc.version.ServiceType serviceType = 1;

Returns:

Whether the serviceType field is set.
