Im trying to export data from HBase Shell to a text file which I can parse, and add to a msysql db.
I am currently using the following command:
echo "scan 'registration',{COLUMNS=>'registration:status'}" | hbase shell > registration.txt
which exports everything from the hbase shell to the registration.txt.
How can I remove the shell intro, and the summary and just append the rows of data to the text file:
Eg: Shell into I want to omit:
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.94.5-mapr, Wed May 1 7:42:07 PDT 2013
Summary I want to omit:
ROW COLUMN+CELL
4419 row(s) in 12.9840 seconds
Try this
echo "scan 'registration',{COLUMNS=>'registration:status'}" | hbase shell | grep "^ " > registration.txt
Since the results are prefixed with single space, remaining stuff would be filtered out.
