duplicates

问题 I have a dataframe loaded from disk df_ = sqlContext.read.json("/Users/spark_stats/test.json") It contains 500k rows. my script works fine on this size, but I want to test it for example on 5M rows, is there a way to duplicate the df 9 times? (it does not matter for me to have duplicates in the df) i already use union but it is really too slow (as I think it keeps reading from the disk everytime) df = df_ for i in range(9): df = df.union(df_) Do you have an idea about a clean way to do that?

问题 I'm building a simple WP plugin that's supposed to create a new post and save some meta for the post. I created a function with the functionality and for the time being I hooked it to the 'init' event to check if it works. add_action( 'init', 'my_func' ); function my_func() { $my_post = array( 'post_title' => 'Some Post Title', 'post_name' => 'some-post-title', 'post_type' => 'custom-post-type', 'post_status' => 'publish' ); $inserted_post_id = wp_insert_post($my_post); if($inserted_post_id !

问题 I have a problem with the GoogleAuthorizationCodeFlow ( Java ). I am trying to build a Google Calender connection for my web project using Google's "OAuth 2.0 for Web Server Applications".

问题 I'm trying to avoid event duplication on same day using full calendar. I have an event called 'Blocked' and if an specific date already have a Blocked event, not allow the user to add another one. My problem is, how to get the list of events at specific day on client side? Here's my code: $(document).ready(function () { $('.calendar').fullCalendar({ dayClick: function (date, jsEvent, view, resourceObj) { // Here I would like to check if this date already have a 'Blocked' event, if yes do not

问题 I got a trouble when a try to execute a trigger. Let's suppose we have 2 tables and I want to copy data from table A to table B but each table got a unique constraint . create table test1 ( test_name varchar); create unique index test1_uc on test1 USING btree (test_name); create table test2 ( test_name2 varchar); create unique index test2_uc on test2 USING btree (test_name2); CREATE OR REPLACE FUNCTION trig_test() RETURNS trigger AS $$ BEGIN IF pg_trigger_depth() <> 1 THEN RETURN NEW; END IF;

问题 I found this absolutely wonderful answer, which helped me cobble together a script. Bear with me, I'm not the most educated at the Google Apps Script, but I'm getting there! Create Google Calendar Events from Spreadsheet but prevent duplicates This is specifically to show how to prevent duplicates, but this is unfortunately my specific problem. I've worked out that it's due to my script not creating the eventids on the spreadsheet, that my script is supposed to recognise and therefore avoid a

问题 As stated in the title, I'm getting duplicate columns with this JOIN query. A few tables are given and I want to write select statements to get only the information from the tables which are needed. Here is my SQL code so far: SELECT mitarbeiter.PNR, pfleger.PNR, Name from pfleger JOIN mitarbeiter on (mitarbeiter.PNR=pfleger.PNR) where Ort='Frankfurt'; After executing, I get the following result: You can see the problem: I have two PNR columns which I don't want to have. How can I remove the

问题 I have a local git repository and I run the following: git.exe pull -v --no-rebase --progress "origin" // pull 1 (make a few local commits) git.exe pull -v --no-rebase --progress "origin" // pull 2 git log --pretty=format:"%h - %an : %s" // log 1 git rebase -i HEAD~4 (move local commit 1 down 2 positions) git log --pretty=format:"%h - %an : %s" // log 2 git.exe pull -v --no-rebase --progress "origin" // pull 3 git log --pretty=format:"%h - %an : %s" // log 3 After doing this all commits to

问题 I have a vector that could look like this: v = [1 1 2 2 2 3 3 3 3 2 2 1 1 1]; that is, the number of equal elements can vary, but they always increase and decrease stepwise by 1. What I want is an easy way to be left with a new vector looking like this: v2 = [ 1 2 3 2 1]; holding all the different elements (in the right order as they appear in v ), but only one of each. Preferably without looping, since generally my vectors are about 10 000 elements long, and already inside a loop that's

问题 I am using the latest IDE for eclipse and have attached the blackberry 5.0 sim. i am a new bb developer and i was wondering if there is any way of integrating java 1.6 classes (or any 3rd party jars) within the blackberry project without getting an error similar to the following: org.apache.axis2.util.Utils$3: Warning!: Duplicate method only differs by return type: run org.apache.axis2.jaxws.util.WSDL4JWrapper: Warning!: Duplicate method only differs by return type: getFirstPortBinding C:
