I have defined a table as such: create external table PageViews (Userid string, Page_View string) partitioned by (ds string) row format as delimited fields terminated by ',' stored as textfile location '/user/data'; I do not want all the files in the /user/data directory to be used as part of the table. Is it possible for me to do the following? location 'user/data/*.csv' I came across this thread when I had a similar problem to solve. I was able to resolve it by using a custom SerDe. I then added SerDe properties which guided what RegEx to apply to the file name patterns for any particular

Log4Net config in external file does not work

由 牧云@^-^@ 提交于 2019-11-27 06:21:46
We are using log4net and want to specify it's configuration in an external config file (as we have done with other sections). To do this we have changed the log4net section in the App.config to: ... <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> ... <log4net configSource="Log.config" /> ... And in the Log.Config file (same directory as the App.config) we have: <log4net> <appender name="General" type="log4net.Appender.FileAppender"> <file value="myapp.log" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> <root> <appender-ref ref="General"

Declaring a global variable `extern const int` in header but only `int` in source file

问题 I was experimenting with GCC and found out that you can declare external variables const in header files but keep them mutable in implementation files. EDIT : This does actually not work. The only reason I got my test code to compile was because I did not include "header.h" in "header.c". header.h: #ifndef HEADER_H_ #define HEADER_H_ extern const int global_variable; #endif header.c: int global_variable = 17; This seems like a very good feature to use for keeping global_variable readonly to

External USB devices to Android phones?

由 天大地大妈咪最大 提交于 2019-11-27 05:35:29
问题 I would like to use Android phones as a way to do some processing and visualization of a sensor that would be attached to the USB port on the phone. The sensor would plug into the micro/mini USB, and then I would need to read the incoming data from the USB serial port. Is this possible? I have heard of people using Android to steer robots and other applications, but I have never seen Android being used as a host for a USB sensor. I can't seem to find any official documentation on the subject

I'm trying this but it is not working: <html> <head> <script src="js/menu-collapser.js" type="text/javascript" media="media screen and (max-width: 599px)"></script> </head> ... </html> //menu-collapser.js : jQuery(document).ready(function($){ $('.main-navigation li ul').hide(); $('.main-navigation li').has('ul').click(function() { $(this).children().toggle(); }); }); Do you have an idea on how to do this in the right way? The script work if used directly in the header with the tags. You can't do that directly using Javascript <script> tags. Media queries are used in linked CSS files or inline

External CSS styles cant be accessed in Google Chrome
