hadoop - Filtering in pig by concatenating two column -

-

मेरे पास निम्न तालिका में दो तालिकाएं हैं

तालिका 1: com_Data

# सीसी बीबी मिमी #

41 22 2563

42 24 3562

तालिका 2:

#name cid #

sasi 41-22-2563

सोमान 42-47-2562

मैं तालिका 1 से तीन कॉलम सीसी बीबी मिमी को जोड़ना चाहता हूं और सभी कॉलम को फ़िल्टर करने की आवश्यकता है तालिका 2 से जो संयुक्त मानों से मेल खाता है

इसे सुअर में कैसे फ़िल्टर करें

जब सुअर का उपयोग करके तीन-स्तंभ अलग-अलग कॉलम को सम्मिलित करने का प्रयास करते हैं तो नीचे दिया गया त्रुटि कोड जो मैंने इस्तेमाल किया 

  a = LOAD 'default.com_data' का उपयोग करना org.apache.hcatalog.pig.HCatLoader (); बी = एक उत्पन्न कॉन्टैक्ट (सीसी, '-', बीबी, '-', मिमी);   
 तालिका को कैसे फ़िल्टर करें?   
 
 
 उसकी तरह दिखें सीसी, बीबी और एमएम के डेटाटाइप संख्याएं हैं। क्या आप डेटैट टाइप को चार्ररा या बायटेयर बदल सकते हैं, ताकि कंसल्ट काम करे कृपया नीचे दिए गए उदाहरण देखें  
  input.txt 41 22 2563 42 24 3562 43 46 1234 इनपुट 1.txt sasi 41-22-2563 सोमान 42-47-2562 परीक्षण 43-46-1234 पईजीस्क्रिप्ट: ए = लोड 'input.txt' का प्रयोग PigStorage ('') एएस (सीसी: चारराय, बीबी: चारराय, मिमी: चारराय); एए = लोड 'input1.txt' का उपयोग PigStorage ('') के रूप में (नाम: chararray, cid: chararray); बी = FOREACH एक जनक CONCAT (सीसी, '-', बीबी, '-', मिमी) newCid के रूप में; सी = सीआईडी ​​द्वारा एए द्वारा जुड़ें, बी द्वारा नए सीआईडी; डी = FOREACH सी उत्पन्न $ 0, $ 1; डंप डी; आउटपुट: (ससी, 41-22-2563) (परीक्षण, 43-46-1234)

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
