How to export data to text file in Apache phoenix?

Question

I'm quite new to HBase and Phoenix.

But is there a way I can dump/export data to a text file? It would be highly appreciable if I can specify the field terminator, such as ',', '|>' etc.

Thanks.

Another Solution.
After connecting to phoenix with sqlline.py:

!outputformat csv
!record data.csv
select * from system.catalog limit 10;
!record
!quit

This seems good except that my output file includes the message "Saving all output to..." and at the end of the select "3 rows selected". Is there a way to get it *only* output the stuff i want? or to skip system messages or something? – mr rogers Sep 02 '16 at 18:28

I have successfully exported, but some numbers are formatted in scientific notation (1,003E+4) when it should simply be an integer (or long float). How do I export the original number not formated? – LuizAngioletti May 22 '18 at 20:27

You can do it with Apache Pherf. Pherf arguments: -export Exports query results to CSV files in CSV_EXPORT directory

I found this link also. But how can I specify the delimiter, for example '|>', I want? A sample code would be highly appreciated. – dehiker Nov 25 '15 at 08:10

Why don't you try using sed once you have generated the dump? – Pratyay May 09 '16 at 07:42

Are you sure this exports query output or the performance testing results ? – iec2011007 May 29 '17 at 11:33

A workaround is to use sed once you have generated the dump. In my case, I wanted a \t de-limiter. However, the column values were of the form 'A','B','C','D' a simple s/','/'\t'/g did the trick for me.
