问题 I need get specific data from gz. how to write the sql? can I just sql as table database?: Select * from gz_File_Name where key = 'keyname' limit 10. but it always turn back with an error. 回答1: You need to create Hive external table over this file location(folder) to be able to query using Hive. Hive will recognize gzip format. Like this: create external table hive_schema.your_table ( col_one string, col_two string ) stored as textfile --specify your file type, or use serde LOCATION 's3:/

问题 I have followed Microsoft's recommended way to unzip a .gz file : https://docs.microsoft.com/en-us/dotnet/api/system.io.compression.gzipstream?view=netcore-3.1 I am trying to download and parse files from the CommonCrawl. I can successfully download them, and unzip them with 7-zip However, in c# I get: System.IO.InvalidDataException: 'The archive entry was compressed using an unsupported compression method.' public static void Decompress(FileInfo fileToDecompress) { using (FileStream

问题 How can you decompress a string of text in Python 3, that has been compressed with gzip and converted to base 64? For example, the text: EgAAAB+LCAAAAAAABAALycgsVgCi4vzcVAWFktSKEgC9n1/fEgAAAA== Should convert to: This is some text The following C# code successfully does this: var gzBuffer = Convert.FromBase64String(compressedText); using (var ms = new MemoryStream()) { int msgLength = BitConverter.ToInt32(gzBuffer, 0); ms.Write(gzBuffer, 4, gzBuffer.Length - 4); var buffer = new byte

问题 I have a gzip file handle that I'm writing to from a multiprocessing pool. Unfortunately, the output file seems to become corrupted after a certain point, so doing something like zcat out | wc gives: gzip: out: invalid compressed data--format violated I'm dealing with the problem by not using gzip. But I'm curious as to why this is happening and if there is any solution. Not sure if it matters, but I'm running the code on a remote linux machine that I don't control but my guess is that it's

问题 I want to compress a string in Dart (in the browser). I tried this: import 'package:archive/archive.dart'; [...] List<int> stringBytes = UTF8.encode(myString); List<int> gzipBytes = new GZipEncoder().encode(stringBytes); String compressedString = UTF8.decode(gzipBytes, allowMalformed: true); Obviously UTF8.decode is not intended for this and it doesn't work (file is unreadable). What is the right way to compress a string in Dart? 回答1: The compressed list of bytes is probably not a valid UTF8

问题 I have created bundles in my asp.net web solution by using the new bundling and minification package by MS. Everything is properly bundled and minified (used global.asax way) but when I deploy on IIS the bundle is not getting compressed (gzip) , I don't want to enable dynamic compression (as it will compress all dynamic content), just want to compress bundles only. What to do ? What is the mime type of a bundled output, like for this bundle named 'Jquery' here : "http://Myhost/MySite/JQuery?v
