Python running on spyder 2.2.5 - python

I am new to Python and trying to run attached code.
import urllib
url = 'https://www.google.com/'
print(url)
sock = urllib.urlopen(url)
But I get an error below:

raise err
IOError: [Errno socket error] [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
Earlier I thought that it is may be because I am running the script from my office and VPN is causing issues. So I ran it from my home internet connection but no resolution :(

Python requests not working for a website API but works in Browser (chrome)

Python requests not working for a website API but works in Browser (chrome). it used to work earlier but from the past 2 months its not working. the api i am using is yts.mx api.
I'll attach the code snippet below:
import requests
a = requests.get('https://yts.mx/api/v2/list_movies.json')
This is the error i am getting:

This used to perfectly work a month ago or so. Tried various methods seen on web.
UPDATE
Turns out the issue is with the IP . When i use a VPN connection it works perfectly. However i dont need a VPN to access it from my web browser. any Idea why this is happening?
is there a way to bypass this?

Since you mentioned, that the browser request goes through but the python request does not, it crossed my mind, that the web site iteself blocks non-browser-requests. I found this question here, that dealt with that problem. The solution was to add a custom header to the python request to make it look like a browser request:
import requests
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.76 Safari/537.36'} # This is chrome, you can set whatever browser you like
url = 'https://yts.mx/api/v2/list_movies.json'
a = requests.get(url,headers)
print(a.content)
With your request, you then send the cutom header as the second parameter in your get-request. I tried the script above and it worked for me, but also your original script worked on my connection.

Connection timeout error while reading a file from HDFS using Python

I have created a single node HDFS in a VM (hadoop.master, IP: 192.168.12.52). The file etc/hadoop/core-site.xml has the following configuration for the namenode:
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://master.hadoop:9000/</value>
</property>
</configuration>
I want to read a file from the HDFS on my local, physical desktop. For that, this is my code, which I've saved in a file named hdfs_read.py:
from hdfs import InsecureClient
client = InsecureClient('http://192.168.12.52:9000')
with client.read('/opt/hadoop/LICENSE.txt') as reader:
features = reader.read()
print(features)
Now when I run it, I get the following timeout error:
$ python3 hdfs_read.py

How can I fix this connection issue? Am I using a wrong port? I though the port that the namenode is using is specified in the core-site.xml, which I have shown above as stating 9000 for the port. In any case, I have tried all the default ports 50070, 8020, 8048 mentioned in the hadoop installation doc for various purposes, and I still get the same error. Instead of client = InsecureClient('http://192.168.12.52:9000'), should I be using client = InsecureClient('hdfs://192.168.12.52:9000'), or maybe client = InsecureClient('file:///192.168.12.52:9000'), or something like that? I have seen these elsewhere at various times.
I can access the HDFS in web by the way, as shown in the screenshot below:
Also, even if it connects successfully, I think I may not be giving the right file path (/opt/hadoop/README.txt). I gave this file path as this is what I see when I do search for the list of files and directories in the hadoop installation directory, which is /opt/hadoop:
$ ls /opt/hadoop/
bin lib read_from_hdfs.py write_to_hdfs_2.py
connect_to_hdfs.py libexec README.txt write_to_hdfs3.py
etc LICENSE.txt sbin write_to_hdfs.py
hdfs_read_write.py logs share
include NOTICE.txt test_storage
But I know that HDFS is separate, and maybe I copied the contents of my HDFS into the local machine by doing hdfs dfs -get /test_storage/ ./ before, which is why its showing these files. But when I search for the files in the path of the namenode, it returns some illegible files:

VERSION
So, if I am specifying the file path to read wrongly, what is the correct file path to use?
EDIT: Upon changing the port to 50070 (i.e., client = InsecureClient('http://192.168.12.52:50070')), I get the following error:

EDIT2: Upon modifying the file path from /opt/hadoop/LICENSE.txt
to /test_storage/LICENSE.txt, which seems to be the correct HDFS path, Iand running the python script, I get the following error:

As stated here link this python library is using webhdfs. If you want to test both the host and the file path are correct you can use the following command curl -i 'http://192.168.12.52:50070/webhdfs/v1/<PATH>?op=LISTSTATUS'. This will list a directory in hdfs. if you get that right you can use the same "config" in python.
from hdfs import InsecureClient
client = InsecureClient('http://192.168.12.52:50070')
with client.read('<hdfs_path>') as reader:
features = reader.read()
print(features)

http://192.168.12.52:9000
9000 is an RPC port. 50070 is the default HTTP WebHDFS port.
You might get No route to host if WebHDFS is disabled, or the datanode is not exposing port 50075 (the datanode http address) because it's down, or you changed that property
client.read('/opt/hadoop/LICENSE.txt')
You're running HDFS in pseudo distributed mode, but you're trying to read a local file. /opt does not exist in HDFS by default, and you've only ran a local ls... You should instead be using hadoop fs -ls /opt to see what files do exist at the path you're trying to open
But when I search for the files in the path of the namenode, it returns some illegible files:
Your files are not stored in the namenode... Their metadata is
Your files are stored in the datanode data directories, but as blocks, not as human-readable content
You can run this command to get a list of all the blocks and their locations
hdfs fsck /path/to/file.txt -files -blocks

There could be a problem with network configuration. Try this tweaked code for the time-being:
from hdfs import InsecureClient
client = InsecureClient('http://0.0.0.0:50070')
with client.read('/test-storage/LICENSE.txt') as reader:
features = reader.read()
print(features)

Hi I'm faced similar issue. It' looks like port is right. Im my case I was able to get list of dirs, but couldn't write any data. Issue was in my vpn which blocks some of the ports, and read and write uses different one.

socket.error: [Errno 111] Connection refused linux

I just started with Nagios XI and i got this error and i cant find the right answer does anyone know what the problem is?
I already checked the proxy and i cant find where the problem is.
The code is to get notifications messages through whats app.

IO error in Python

I am trying to run this code:
import urllib
htmlfile = urllib.urlopen("https://www.google.co.in/?gfe_rd=cr&ei=7VzrV6WWG8KC0ATxor_IDw")
htmltext = htmlfile.read()
print htmltext
But the following error is shown, when I run the code:

Can anyone tell why this error occurs?

It's a connection problem (your code works on my computer). Check your firewall / proxy settings / dns server / other connection settings.

It looks like you have a flakey internet connection. The error "Name or service not known" means the DNS lookup for the page failed, the "Connection timed out error" means you were unable to contact the remote server but the DNS lookup succeeded.
