getPreferredProperty

public static String getPreferredProperty(NiFiProperties properties,
 String preferredPropertyName,
 String defaultPropertyName)

Retrieves the preferred property value if it's set, otherwise retrieves the default property. If neither are set, returns null.

Parameters:

properties - The NiFi properties configuration.

preferredPropertyName - The preferred property to get from NiFi properties.

defaultPropertyName - The backup property to get from NiFi properties if the preferred property is not present.

Returns:

Returns the property in order of preference.

cleanConnectString

public static String cleanConnectString(String connectString)

Takes a given connect string and splits it by ',' character. For each split result trims whitespace then splits by ':' character. For each secondary split if a single value is returned it is trimmed and then the default zookeeper 2181 is append by adding ":2181". If two values are returned then the second value is evaluated to ensure it contains only digits and if not then the entry is in error and exception is raised. If more than two values are returned the entry is in error and an exception is raised. Each entry is trimmed and if empty the entry is skipped. After all splits are cleaned then they are all appended back together demarcated by "," and the full string is returned.

Parameters:

connectString - the string to clean

Returns:

cleaned connect string guaranteed to be non null but could be empty

Throws:

IllegalStateException - if any portions could not be cleaned/parsed
