Constructor Detail

ZooKeeperSeedNodeProviderConfig

public ZooKeeperSeedNodeProviderConfig()

Method Detail

getConnectionString

public String getConnectionString()

Returns the list of ZooKeeper servers to connect to (see setConnectionString(String)).

Returns:

ZooKeeper connection string.

setConnectionString

public void setConnectionString(String connectionString)

Set the list of ZooKeeper servers to connect to.

Connection string can be specified as a comma-separated list of host:port addresses (f.e. 127.0.1:2181,127.0.01:2182)

Parameters:

connectionString - Comma-separated list of addresses.

withConnectionString

public ZooKeeperSeedNodeProviderConfig withConnectionString(String connectionString)

Fluent-style version of setConnectionString(String).

Parameters:

connectionString - Comma-separated list of addresses.

Returns:

This instance.

getConnectTimeout

public int getConnectTimeout()

Returns the ZooKeeper connection timeout in milliseconds (see setConnectTimeout(int)).

Returns:

Timeout in milliseconds.

setConnectTimeout

public void setConnectTimeout(int connectTimeout)

Sets the ZooKeeper connection timeout in milliseconds.

Default value of this parameter is 5000.

Parameters:

connectTimeout - Timeout in milliseconds.

withConnectTimeout

public ZooKeeperSeedNodeProviderConfig withConnectTimeout(int connectTimeout)

Fluent-style version of setConnectTimeout(int).

Parameters:

connectTimeout - Timeout in milliseconds.

Returns:

This instance.

getSessionTimeout

public int getSessionTimeout()

Returns the ZooKeeper session timeout in milliseconds (see setSessionTimeout(int)).

Returns:

Timeout in milliseconds.

setSessionTimeout

public void setSessionTimeout(int sessionTimeout)

Sets the ZooKeeper session timeout in milliseconds.

Note that ZooKeeperSeedNodeProvider uses short-lived connection when interacting with ZooKeeper server (i.e. it creates a new connection for each operation and then closes it once operation is complete). Thus, it is not necessary to set this parameter to a large value.

Default value of this parameter is 10000.

Parameters:

sessionTimeout - Timeout in milliseconds.

withSessionTimeout

public ZooKeeperSeedNodeProviderConfig withSessionTimeout(int sessionTimeout)

Fluent-style version of setSessionTimeout(int).

Parameters:

sessionTimeout - Timeout in milliseconds.

Returns:

This instance.

getBasePath

public String getBasePath()

Returns the base path to store seed nodes information in ZooKeeper (see setBasePath(String)).

Returns:

Base path to store seed nodes.

setBasePath

public void setBasePath(String basePath)

Sets the base path to store seed nodes information in ZooKeeper.

Default value of this parameter is "/hekate/cluster".

Parameters:

basePath - Base path to store seed nodes.

withBasePath

public ZooKeeperSeedNodeProviderConfig withBasePath(String basePath)

Fluent-style version of setBasePath(String).

Parameters:

basePath - Base path to store seed nodes.

Returns:

This instance.

getCleanupInterval

public int getCleanupInterval()

Returns the time interval in milliseconds between stale node cleanup runs (see setCleanupInterval(int)).

Returns:

Time interval in milliseconds.

setCleanupInterval

public void setCleanupInterval(int cleanupInterval)

Sets the time interval in milliseconds between stale node cleanup runs.

Default value of this parameter is 60000.

For more details please see the documentation of SeedNodeProvider.

Parameters:

cleanupInterval - Time interval in milliseconds.

See Also:

SeedNodeProvider.cleanupInterval()

withCleanupInterval

public ZooKeeperSeedNodeProviderConfig withCleanupInterval(int cleanupInterval)

Fluent-style version of setCleanupInterval(int).

Parameters:

cleanupInterval - Time interval in milliseconds.

Returns:

This instance.

toString

public String toString()

Overrides:

toString in class Object
