Examples with ServerInfo org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.ServerInfo used on opensource projects

Example 1 with ServerInfo

use of org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.ServerInfo in project hbase by apache.

the class DistributedHBaseCluster method getServerHoldingRegion.

@Override
public ServerName getServerHoldingRegion(TableName tn, byte[] regionName) throws IOException {
    HRegionLocation regionLoc = null;
    try (RegionLocator locator = connection.getRegionLocator(tn)) {
        regionLoc = locator.getRegionLocation(regionName, true);
    }
    if (regionLoc == null) {
        LOG.warn("Cannot find region server holding region " + Bytes.toString(regionName) + ", start key [" + Bytes.toString(HRegionInfo.getStartKey(regionName)) + "]");
        return null;
    }
    AdminProtos.AdminService.BlockingInterface client = ((ClusterConnection) this.connection).getAdmin(regionLoc.getServerName());
    ServerInfo info = ProtobufUtil.getServerInfo(null, client);
    return ProtobufUtil.toServerName(info.getServerName());
}

Example 2 with ServerInfo

use of org.apache.hadoop.hbase.shaded.protobuf.generated.AdminProtos.ServerInfo in project hbase by apache.

the class ServerManager method isServerReachable.
