Вопрос
I need some data out of my hypertable. I can inspect the data with the hypertable shell and was curios whether it is possible to pipe the result of a HQL query into a file. This would be useful for further investigations when the result set is large and one wants to format it or something else.
Any ideas?

sure:
SELECT * FROM table INTO FILE "file.txt";
You can even compress the file:
SELECT * FROM table INTO FILE "file.txt.gz";
Type help select
in the shell and you will get more info.
