I am new to spark scala and I have following situation as below I have a table "TEST_TABLE" on cluster(can be hive table) I am converting that to dataframe as: scala> val testDF = spark.sql("select * from TEST_TABLE limit 10") Now the DF can be viewed as scala> testDF.show() COL1|COL2|COL3 ---------------- abc|abcd|abcdef a|BCBDFG|qddfde MN|1234B678|sd I want an output like below COLUMN_NAME|MAX_LENGTH COL1|3 COL2|8 COL3|6 Is this feasible to do so in spark scala? Plain and simple: import org.apache.spark.sql.functions._ val df = spark.table("TEST_TABLE") df.select(df.columns.map(c => max

Making sure length of matrix row is all the same (python3)

女生的网名这么多〃 提交于 2019-12-02 08:04:01
so I have this python 3 code to input a matrix: matrix = [] lop=True while lop: line = input() if not line: lop=False if matrix != []: if len(line.split()) != len(matrix[-1]): print("Not same length") menu() values = line.split() row = [int(value) for value in values] matrix.append(row) However,if I enter 1 2 3 4 5 6 7 8 9 0 1 2 my code will let it pass,but you can notice that row 2 and 3 are not same length as row 1; how to prevent that? the row have to be same length as row 1,else it has to return an error message like 'line don't have the same length. I'm not quite sure of how to do that.

Different maxlength validation of textarea with newlines in Chrome and Firefox

瘦欲@ 提交于 2019-12-01 18:06:27
The problem is that Firefox counts newline as "1" (\n) character while Chrome count them as "2" (\r\n) This is what I get in a textarea with maxlength=10 : This are 10 charcters for Firefox 1234 5 6 7 This are 10 charcters for Chrome 1234 5 6 The problem comes when trying to validate the form. If I have for example the following text 012345 678 In Firefox the validation passes and the data is saved, but when I try to do the same in Chrome it shows a warning, and prevents it from sending the form. "Please shorten this text to 10 characters or less(you are currently using 11 characters)" . I

Creating an empty deque in Python with a max length?

…衆ロ難τιáo~ 提交于 2019-12-01 05:39:51
I'm looking at the documentation for a Python deque, and it looks like the constructor is deque([iterable[, maxlen]]) . Is there no way to make an empty deque (that is, without specifying the iterable) with a max length? You could provide a list literal directly, so you don't have to declare anything on a separate line: >>> collections.deque([], 42) deque([], maxlen=42) You could also provide maxlen as a named argument: >>> collections.deque(maxlen=23) deque([], maxlen=23) 来源: https://stackoverflow.com/questions/26124816/creating-an-empty-deque-in-python-with-a-max-length

Groovy says my Unicode string is too long

荒凉一梦 提交于 2019-12-01 04:44:54
As part of my probably wrong and cumbersome solution to print out a form I have taken a MS-Word document, saved as XML and I'm trying to store that XML as a groovy string so that I can ${fillOutTheFormProgrammatically} However, with MS-Word documents being as large as they are, the String is 113100 unicode characters and Groovy says its limited to 65536. Is there some way to change this or am I stuck with splitting up the string? Groovy - need to make a printable form That's what I'm trying to do. Update: to be clear its too long of a Groovy String.. I think a regular string might be all good.

How reliable is the MaxLength property of the TextBox-Control?

荒凉一梦 提交于 2019-11-30 21:34:10
The TextBox control offers a MaxLength property, which allows the insertable text into that TextBox be clientside limited to the specified amount of chars. My questions : Is this property only client-side and therefore browser-pedendent? Can I rely on the fact, that the Text property contains no text longer than MaxLength is set (only for the DisplayModes named in the MSDN article) or do I manually have to perform a TextBox.Text.SubString(0, DesiredMaxLength) ? How does all this behave with disabled java-script? It does not depend on javascript but that does not make it safe. Anyone can still

Enforcing the maxlength attribute on mobile browsers

大兔子大兔子 提交于 2019-11-30 17:58:30
I have an a text input with a maximum length: <input type="text" name="name" maxlength="50"> This has been working fine on all the desktop browsers I've tried, but the maximum length does not seem to be enforced on mobile browsers. Is there any way to get mobile browsers to enforce maxlength ? I am open to using JavaScript and/or jQuery in the solution. Try this one: var $input = $('input') $input.keyup(function(e) { var max = 5; if ($input.val().length > max) { $input.val($input.val().substr(0, max)); } }); jsFiddle here: http://jsfiddle.net/fttk2/1/ var max = 1 input.addEventListener('keyup'
