Example 1 with OpRequestShortCircuitAccessProto

use of org.apache.hadoop.hdfs.protocol.proto.DataTransferProtos.OpRequestShortCircuitAccessProto in project hadoop by apache.

the class Receiver method opRequestShortCircuitFds.

/** Receive {@link Op#REQUEST_SHORT_CIRCUIT_FDS} */
private void opRequestShortCircuitFds(DataInputStream in) throws IOException {
    final OpRequestShortCircuitAccessProto proto = OpRequestShortCircuitAccessProto.parseFrom(vintPrefixed(in));
    SlotId slotId = (proto.hasSlotId()) ? PBHelperClient.convert(proto.getSlotId()) : null;
    TraceScope traceScope = continueTraceSpan(proto.getHeader(), proto.getClass().getSimpleName());
    try {
        requestShortCircuitFds(PBHelperClient.convert(proto.getHeader().getBlock()), PBHelperClient.convert(proto.getHeader().getToken()), slotId, proto.getMaxVersion(), proto.getSupportsReceiptVerification());
    } finally {
        if (traceScope != null)
            traceScope.close();
    }
}

Example 2 with OpRequestShortCircuitAccessProto

use of org.apache.hadoop.hdfs.protocol.proto.DataTransferProtos.OpRequestShortCircuitAccessProto in project hadoop by apache.

the class Sender method requestShortCircuitFds.
