Example 1 with RollingUpgradeStatus

use of org.apache.hadoop.hdfs.protocol.RollingUpgradeStatus in project hadoop by apache.

the class DatanodeProtocolServerSideTranslatorPB method sendHeartbeat.

@Override

    RollingUpgradeStatus rollingUpdateStatus = response.getRollingUpdateStatus();
    if (rollingUpdateStatus != null) {
        // V2 is always set for newer datanodes.
        // To be compatible with older datanodes, V1 is set to null
        //  if the RU was finalized.
