public static ZooReaderWriter getInstance(String zooConnString,
                                          int timeInMillis,
                                          String secret)

This method exposes the zookeeper connection parameters when instantiating a cached singleton ZooReaderWriter instance for later use in testing. The instance will only be created once, otherwise the previously cached instance is returned.

Parameters:

zooConnString - a zookeeper connection string of host:port pair of server(s)

timeInMillis - the zooKeeper connection timeout

secret - the Accumulo instance secret

Returns:

a ZooReaderWriter instance either created or previously cached.
