Constructor Detail

AbstractBigtableConnection

public AbstractBigtableConnection(org.apache.hadoop.conf.Configuration conf)
                           throws IOException

Constructor for AbstractBigtableConnection.

Parameters:

conf - a Configuration object.

Throws:

IOException - if any.

AbstractBigtableConnection

protected AbstractBigtableConnection(org.apache.hadoop.conf.Configuration conf,
                                     boolean managed,
                                     ExecutorService pool,
                                     User user)
                              throws IOException

The constructor called from ConnectionFactory.createConnection(Configuration) and in its many forms via reflection with this specific signature.

Parameters:

conf - The configuration for this channel. See BigtableOptionsFactory for more details.

managed - This should always be false. It's an artifact of old HBase behavior.

pool - An ExecutorService to run HBase/Bigtable object conversions on. The RPCs themselves run via NIO, and not on a waiting thread

user - This is an artifact of HBase which Cloud Bigtable ignores. User information is captured in the Credentials configuration in conf.

Throws:

IOException - if the setup is not correct. The most likely issue is ALPN or OpenSSL misconfiguration.
