Is there any way I can output the results from a scan in the hbase shell to a file? I'm assuming this is easy but I haven't been able to find anything in the documentation.
I know that this post is quite old but i was searching something about HBase myself and came across with it.
Well i don't know if this is the best way to do it, but you can definitely use the scripting option HBase gives you. Just open a shell (preferably go to the directory bin of HBase) and run
echo "scan 'foo'" | ./hbase shell > myText
where foo is the name of the table you want to scan. If you then open myText you will see the results in there. Hope i helped!
Another option using an EOF here doc, potentially more customizable:
hbase shell <<EOF >myText
scan 'foo'
EOF
You can also use here strings too (if your shell supports them):
$ hbase shell <<< "scan 'sometable'" > myoutput.txt
Above I'm doing this in Bash on a Linux system, for example.
