Formatting result from scan command in HBASE

Question

I am trying to run 'scan' command on HABSE shell.

scan 'table_name'

I am getting result as this:

ROW                             COLUMN+CELL                                                                             

000001bff3df$94a8a4c0$608812cf column=general:bcc, timestamp=1521624689099, value=

If you look at the result, it is not well formatted. I could not figure out what is ROW and what is COLUMN+CELL.

Que. Is there any way I can format this result for better readability?

Answer 1

The hbase shell is not displaying the result properly due to terminal window limitation. Tr o output the scan result to a file.

• Go to shell command prompt (not in hbase shell )

• Execute the below command

  echo "scan 'table_name'" | hbase shell > myText

The output in mytext would not be wrapped on key . Once you have data in the file, you can use shell commands to format is further as per your requirement.

Answer 2

This behavior seems to depend on terminal settings. I see column wrapping when I have TERM=dumb in my environment variables. I don't see it when I have TERM=xterm or TERM=ansi
