Method Detail

parse
```
public void parse(String path)
           throws QuorumPeerConfig.ConfigException
```
Parse a ZooKeeper configuration file

Parameters:

path - the patch of the configuration file

Throws:

QuorumPeerConfig.ConfigException - error processing configuration

getVersionFromFilename

public static String getVersionFromFilename(String filename)

parseProperties

public void parseProperties(Properties zkProp)
                     throws IOException,
                            QuorumPeerConfig.ConfigException

Parse config from a Properties.

Parameters:: zkProp - Properties to parse from.
Throws:: IOException; QuorumPeerConfig.ConfigException

configureSSLAuth
```
public static void configureSSLAuth()
                             throws QuorumPeerConfig.ConfigException
```
Configure SSL authentication only if it is not configured.

Throws:

QuorumPeerConfig.ConfigException - If authentication scheme is configured but authentication provider is not configured.

writeDynamicConfig

public static void writeDynamicConfig(String dynamicConfigFilename,
                                      QuorumVerifier qv,
                                      boolean needKeepVersion)
                               throws IOException

Writes dynamic configuration file

Throws:: IOException

editStaticConfig
```
public static void editStaticConfig(String configFileStr,

                             throws IOException
```
Edit static config file. If there are quorum information in static file, e.g. "server.X", "group", it will remove them. If it needs to erase client port information left by the old config, "eraseClientPortAddress" should be set true. It should also updates dynamic file pointer on reconfig.

Throws:

IOException
