ENODE_OPTS. Using value of HADOOP_SECONDARYNAMENODE_OPTS.

关于ENODE_OPTS的问题，ENODE_OPTS是一个环境变量，它用于设置Hadoop的NameNode进程的参数。在这种情况下，它的值是根据HADOOP_SECONDARYNAMENODE_OPTS来设置的。这意味着ENODE_OPTS的值将与HADOOP_SECONDARYNAMENODE_OPTS相同。

Unfortunately, the given code snippet is incomplete and contains syntax errors. However, I will provide a rough translation of the code to Python, assuming that the missing parts are defined elsewhere in the code:

class Node:
    def __init__(self, cw=0, cp=0, i=0, flag=0, par=0):
        self.cw = cw
        self.cp = cp
        self.i = i
        self.flag = flag
        self.par = par

n = ...
m = ...

enode = Node()
enode.cw = 0
enode.cp = 0
enode.i = 0
enode.flag = 0
enode.par = 0

q = [Node() for _ in range(100)]
g = [Node() for _ in range(n)]
f = 0
e = 0
bestp = 0
beste = 0

e += 1
g[e] = enode

while e != 0:
    node = Node()
    node.cw = enode.cw + w[enode.i + 1]
    if node.cw <= m:
        node.cp = enode.cp + p[enode.i + 1]
        if node.cp > bestp:
            bestp = node.cp
            beste = e + 1
        node.flag = 1
        node.par = f
        node.i = enode.i + 1
        e += 1
        q[e] = node
    node.cw = enode.cw
    node.cp = enode.cp
    node.flag = 0
    node.par = f
    node.i = enode.i + 1
    e += 1
    q[e] = node
    f += 1
    enode = q[f]

for j in range(n, l+1):
    if q[beste].flag == 1:
        print("choose", q[beste].i)
    beste = q[beste].par

print("Max=", bestp)

Note that this translation may not work as expected, since the original code is incomplete and contains syntax errors. Furthermore, I had to make some assumptions about the missing parts of the code, so the translation may not be accurate.

BaiduNaviManagerFactory.getRoutePlanManager().routePlan

要使用百度地图导航SDK进行路线规划，您可以按照以下步骤调用`BaiduNaviManagerFactory.getRoutePlanManager().routePlan()`方法：

1. 创建起点、终点和途径点的`BNRoutePlanNode`对象。您可以使用`BNRoutePlanNode.Builder`类来构建节点对象。例如：

   BNRoutePlanNode sNode = new BNRoutePlanNode.Builder()
           .latitude(startLat)
           .longitude(startLng)
           .name("起点")
           .build();
   
   BNRoutePlanNode eNode = new BNRoutePlanNode.Builder()
           .latitude(endLat)
           .longitude(endLng)
           .name("终点")
           .build();
   
   BNRoutePlanNode viaNode = new BNRoutePlanNode.Builder()
           .latitude(viaLat)
           .longitude(viaLng)
           .name("途径点")
           .build();

在上述代码中，您需要将`startLat`、`startLng`、`endLat`、`endLng`、`viaLat`和`viaLng`替换为实际的起点、终点和途径点的经纬度。

2. 创建一个`ArrayList<BNRoutePlanNode>`对象，并将起点、终点和途径点添加到列表中：

   ArrayList<BNRoutePlanNode> nodes = new ArrayList<>();
   nodes.add(sNode);
   nodes.add(eNode);
   nodes.add(viaNode);

3. 调用`BaiduNaviManagerFactory.getRoutePlanManager().routePlan()`方法进行路线规划：

   BaiduNaviManagerFactory.getRoutePlanManager().routePlan(
           YourActivity.this, nodes, 
           BaiduNaviManager.RoutePlanPreference.ROUTE_PLAN_MOD_MIN_TIME, 
           new BaiduNaviManager.RoutePlanListener() {
               @Override
               public void onJumpToNavigator(Bundle bundle) {
                   // 路线规划成功后的回调，可以在此处启动导航页面
                   Intent intent = new Intent(YourActivity.this, YourNavigatorActivity.class);
                   intent.putExtras(bundle);
                   startActivity(intent);
               }
   
               @Override
               public void onRoutePlanFailed() {
                   // 路线规划失败的回调
               }
           });

在上述代码中，`YourActivity`是您当前的Activity类名，`YourNavigatorActivity`是您用于显示导航界面的Activity类名。

通过以上步骤，您就可以使用百度地图导航SDK进行路线规划，并在规划成功后启动导航页面。请确保已正确配置百度地图导航SDK，并在AndroidManifest.xml文件中添加相应的权限和配置。
