You don't have to run the major compaction - the shell is doing that for
you. You must disable the table first, like:
disable 'session_timeline'
drop 'session_timeline'
See the admin.rb file:
def drop(table_name)
tableExists(table_name)
raise ArgumentError, "Table #{table_name} is enabled. Disable it
first.'" if enabled?(table_name)
@admin.deleteTable(table_name)
flush(org.apache.hadoop.hbase.HConstants::META_TABLE_NAME)
major_compact(org.apache.hadoop.hbase.HConstants::META_TABLE_NAME)
end
