QUESTION
Based on my previous question, I built a simple JSON file with one "row" per line. I'm still in shock, because this is not valid JSON, as it doesn't have square brackets around it.
One data file:
...ANSWER
Answered 2020-Oct-23 at 16:55Glue is terrible in general, but this actually surprised me until I saw the comment by Achyut: your JSON is malformed.
JSON is a data format, not a file format. There is no such thing as a correctly formatted JSON file because the specification doesn't cover that. Tools like Spark, Hadoop, and Athena require JSON data to be in files with one document per line, because that makes it easy to efficiently process the data. Sometimes this is referred to as "JSON stream" (which isn't a great name since we're talking about files), or "line-delimited JSON".
I think you will be better off just creating the table manually. You can find an example to start off from in the documentation: https://docs.aws.amazon.com/athena/latest/ug/json-serde.html
You should also use a proper JSON serialisation library for writing your JSON so that you don't end up with syntax errors like that accidental comma instead of colon.
QUESTION
I'm putting JSON data files into S3, and use AWS-Glue to build the table definition. I have about 120 fields per each json "row". One of the fields is called "timestamp" in lower case. I have 1000s of large files, and would hate to change them all.
Here (https://docs.aws.amazon.com/athena/latest/ug/reserved-words.html), I see TIMESTAMP in DDL is a reserved word. Does that mean I won't be able to read those JSON file from Athena.
I'm getting this error, which lead me to the above being a potential reason.
I clicked the 3 dots to the right of the tablename, and clicked "Preview Table", which built and ran this select statement:
...ANSWER
Answered 2020-Oct-23 at 07:43It's very easy to get Glue crawlers to create tables that don't work in Athena, which is surprising given that it's the primary goal it was designed for.
If the JSON you posted is exactly what you ran your crawler against the problem is that Athena does not support multi-line JSON documents. Your files must have exactly one JSON document per line. See Dealing with multi-line JSON? (And, bonus points, CRLF), Multi-line JSON file querying in hive, and Create Table in Athena From Nested JSON

Answered 2020-Aug-31 at 09:34parses fine? I see at https://docs.python.org/3/reference/expressions.html#operator-precedence that not is lower than +, but to me, that doesn't really explain why it can't parse 3 + not 2.
Meant you try to calculate like (3 + not) 2 which is wrong: "not" operator not suitable for "+" operator as operand.
QUESTION
I've been trying to run my nuxt app in docker and the build seem to work for the most part other than it keep missing core.js dependencie. I've tried adding core-js manually, babel, tried to run the suggested install command in the error, but to no help.
Dockerfile:
...ANSWER
Answered 2020-Jun-22 at 15:38This had nothing to do with docker. I'm not sure how, but at some point reinstalling all the node modules installed the wrong core-js version.
Installing "core-js": "^2"
seems to have solved it for now. Perhaps upgrading nuxt version would help too.
QUESTION
I found myself calling lots of methods whose first argument is a complex object from a given class. Whilst with-slots and with-accessors are useful, generic methods cannot be bound in this way. So I thought: if we could locally curry any functions, slots + accessors + generic functions + functions could all be addressed with the same construct.
Example of code I want to clean up:

QUESTION
I'm trying to install create-react-app
in my project, but a package.json without a start script is generated, and I get an error "A template was not provided. This is likely because you're using an outdated version of create-react-app.
Please note that global installs of create-react-app are no longer supported." As recommended in other questions regarding this issue, here's what I've already tried:
npm uninstall -g create-react-app
, which create-react-app
then rm -rf [the path that was listed]
(now when I enter which create-react-app
it says which: no create-react-app in .....
, and restarted my computer.
I don't know what else to try. Any help appreciated.
Here is my full error message/what I get when trying to run create-react-app:
...ANSWER
Answered 2019-Dec-18 at 22:10So the best thing to do is to remove create-react-app
globally using npm uninstall create-react-app -g
or yarn global remove create-react-app
because that is likely the reason you're seeing this error message:
This is likely because you're using an outdated version of create-react-app. Please note that global installs of create-react-app are no longer supported.
Once you've removed it, please note you don't need to install create-react-app
globally to initialize a new project, its recommended you use the npx
package runner tool that comes with at least node 5.2
and above. So npx
will basically allow you to run a package without installing it, so on your case create-react-app
.
So to create a new project, just type in : npx create-react-app myapp
and that will initialize your react app.
QUESTION
The lists of reserved keywords don't include "arguments". Should they? I don't see how "arguments" could be used as an identifier.
...ANSWER
Answered 2019-Nov-21 at 07:00There are several keyword-like things (or even actual keywords) that aren't reserved words in JavaScript (and thus TypeScript); details here. arguments
isn't a keyword, it's an implicitly-declared binding (like a variable) within traditional functions (ones using the function
keyword) and methods (declared with method syntax in classes or object literals). That means you can shadow it, declare it in a context that doesn't already have it, etc.
I don't see how "arguments" could be used as an identifier.
It can be, but only in loose mode. Here are some examples:
