      HBASE-24776 added the following command line parameters to hbtop:
      | Argument | Description |
      |---|---|
      | -n,--numberOfIterations <arg> | The number of iterations |
      | -O,--outputFieldNames | Print each of the available field names on a separate line, then quit |
      | -f,--fields <arg> | Show only the given fields. Specify comma separated fields to show multiple fields |
      | -s,--sortField <arg> | The initial sort field. You can prepend a `+' or `-' to the field name to also override the sort direction. A leading `+' will force sorting high to low, whereas a `-' will ensure a low to high ordering |
      | -i,--filters <arg> | The initial filters. Specify comma separated filters to set multiple filters |
      | -b,--batchMode | Starts hbtop in Batch mode, which could be useful for sending output from hbtop to other programs or to a file. In this mode, hbtop will not accept input and runs until the iterations limit you've set with the `-n' command-line option or until killed |

      Description

      Similar to Unix's 'top' command, we can support Batch mode that allows us to send hbtop command output to other programs or to a file.
