I am using Scala spark streaming , and I need to push my results to a kafka topic. I am using .selectExpr("to_json(struct(Column1,Column2,Column3,Column4))as value") .
And I get the result:
{"Column1":"Value_Column1","Column4":"Value_Column4"}
{"Column1":"Value_Column1","Column2":"Value_Column2"}
{"Column1":"Value_Column1","Column3":"Value_COlumn3"}
How should I change the .selectExpr or what are the steps I need to take to get an output like this :
{"Column1":"Value_Column1","Column2":"Value_Column2","Column3":"Value_Column3","Column4":"Value_Column4"}
Thank you all in advance!
We are currently working on getting all the keys in Memcached through:
lru_crawler metadump all
For this implementation, we are expecting END or OK at the end of result.
But Memcached doesn't return any response code after the end of data. It just simply returns the metadata.
lru_crawler metadump 1
key=key exp=-1 la=1588598718 cas=1 fetch=no cls=1 size=80
We are using Memcached version 1.4.33.
Is there any configuration that we need to set up for this to return a response code at the end (or) Is there any way that we can find the end of metadump result other than END or OK?
Thanks in advance.
Seems it is a known issue with the Memcahed
https://github.com/memcached/memcached/issues/667
(came across this post when researching a project I'm working on)
It is no longer an issue in current memcache implementations - I'm using 1.5.6 and get 'END'. However it is my experience that this does not always return the full list. I suspect that may be due the order of items in the LRU list changing while command is running (I get 99-100% of the keys when the server is getting hammered).
Is there any scenario that explains why the update is not working, I can't seem to pinpoint the cause and I don't see any errors whatsoever. Is there a way to check the output of the update function because currently the update is not doing anything. That means the last log line shows a value different than 20170615-7702.
Db.find().forEach(function(item){
console.log(item._id+ " =======> " + item.build.parameters.BUILD_NUM);
Db.update({"_id":item._id}, {$set:{"build.parameters.BUILD_NUM":"20170615-7702"}});
console.log(Db.findOne({"_id": item._id}).build.parameters.BUILD_NUM);});
Thank you
The code above should work. I think that the problem above is that it is not able to update the document as fast as it prints the output. First try:
var itemUpdated = Db.findOne({"_id": item._id});
console.log(itemUpdated._id)
The other option is very simple go to the command line and run meteor mongo. Then see all the entries in the collection and their properties.
Third and maybe the best option to test here is to use setTimeout() for the console.log().
Hope it helps.
I am using zend_lucene for search functionality.I 've the following code,
$doc->addField(Zend_Search_Lucene_Field::Text('categoryName', $result->name));
Here name in "$result->name" is varchar type in Database. Also have some following values like dinesh,kumar123,3333. For testing purpose i have stored number in name field. when i search dinesh , Search comes with exact result but when i use number search, That is 3333 Search has no result. What i done wrong on the code Zend_Search_Lucene_Field::Text.
Is there any way for search number/char/alphanumeric (kumar123) ?
Thanks in Advance
Finally i found by declaring "Zend_Search_Lucene_Analysis_Analyzer::setDefault(new Zend_Search_Lucene_Analysis_Analyzer_Common_TextNum_CaseInsensitive());" and use Zend_Search_Lucene_Field::Keyword instead of Zend_Search_Lucene_Field::Text
Using Foursquare api "Venue" service.. i am parsing nearByVenue details like shop, restaurant etc.
Suppose as an example i am getting following link:
https://api.foursquare.com/v1/venues.json?geolat=40.562362&geolong=-111.938689
Issue is I am getting only 10 nearbyDetails.. suppose I am standing in New York there should be number of venue details.. why I am getting only 10 details only ?
Is there any other service or i am following wrong approach to use it?
Thanks
Add l=n where n is your limit in query string. The default limit is set to 30.
https://api.foursquare.com/v1/venues.json?geolat=40.562362&geolong=-111.938689&l=10
https://api.foursquare.com/v1/venues.xml?geolat=40.562362&geolong=-111.938689&l=50&q=coffee
You can change the value of l="no of result" parameter.
And also if you want to search for particular keyword like ATM, Coffee
then you can add the parameter q and add it's value like q="atm", q="coffee", etc.
hope it will be helpful to you.
