AceHelper

public AceHelper()

Method Details

getPermissionsListForShellHelp

public static String getPermissionsListForShellHelp()

Helper method used by HBase shell to print all applicable permissions. Since HBase releases are not tied to a particular MapR release, this will ensure that any supported version of HBase shell will display correct help message applicable for the deployed version of MapR release.

Returns:

Help text to be displayed by HBase shell permission commands.

toInfix

public static String toInfix(String postfix)
                      throws IOException

Converts postfix string into infix string Examples: "u:1 g:1 |" => "u:1 | g:1" "u:1 g:123 g:3 r:12 | & p & |" => "u:1 | ((g:123 & (g:3 | r:12)) & p)"

Parameters:

postfix - The postfix string to convert

Returns:

Converted infix string

Throws:

IOException

toPostfix

public static String toPostfix(String permission)
                        throws IOException

Method to convert infix statement to postfix Examples: "u:1 | g:1" => "u:1 g:1 |" "u:1 | ((g:123 & (g:3 | r:12)) & p)" => "u:1 g:123 g:3 r:12 | & p & |"

Parameters:

permission - The permission string in infix format to be converted

Returns:

The permission string converted to postfix notation

Throws:

IOException
