Hi Jiajun,

There's a script in hbase/bin to add a table: you can run bin/hbase org.jruby.Main bin/add_table.rb

Also there's a setting for HDFS to enable trash. This way your files won't get directly deleted, but rather moved the Trash. You can later restore them or purge them (see HDFS doc

Good luck,
Cosmin

Thank you

bin/hbase org.jruby.Main bin/add_table.rb /hbase/cjjProgramme cjjProgramme
bin/add_table.rb:80: Not supported yet (IOError)

My HBase's version is 0.20.6 and HDFS version is 0.20.2.

Yep,

Just checked out 0.20 and tried it.

Look into add_table.rb

# Get table name
tableName = nil
if ARGV.size > 1
  tableName = ARGV[1]
  raise IOError.new("Not supported yet")
elsif
You can't provide a table name. Run the script with just the path to the table (no table name as the second argument)

It worked.

Good luck,
Cosmin

Also 0.20 is very old. You should upgrade to 0.90 asap  ;)
