NodeJs imapala查询无响应

Question

我正在运行此nodejs函数，该函数查询impala查询并返回一些结果

import tensorflow as tf
def mean_var(x):
    vec = tf.random_normal([x])
    mean, variance = tf.nn.moments(vec, [0], keep_dims=True)
    return  mean, variance 
with tf.Graph().as_default():
    x = tf.placeholder(tf.int32)
    output = mean_var(x)
    init = tf.initialize_all_variables()
    _ = tf.Variable(initial_value='fake_variable')
    saver = tf.train.Saver()


    with tf.Session() as sess:
        sess.run(init)
        sess.run(_.initializer)
        #val = sess.run(output, feed_dict={x: 4})
        #print(val[0], val[1])
        save_path = saver.save(sess, "./mean_var.ckpt")

tf.reset_default_graph()

with tf.Graph().as_default():
    init = tf.initialize_all_variables()
    _ = tf.Variable(initial_value='fake_variable')
    saver = tf.train.Saver()
    with tf.Session() as sess:
        sess.run(init)
        sess.run(_.initializer)
        saver.restore(sess, './mean_var.ckpt')

但是我的代码被卡住了，就像在“ resultset.toObjArray”上花费2-3分钟一样，对于具有大量行的查询没有错误， 同样，CPU会在此声明中使用100％的代码，有什么办法可以解决这个问题？
