[jira] [Commented] (ACCUMULO-3742) Multiple-valued client properties don't work

["Billie Rinaldi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-3742?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14503590#comment-14503590 ] 

Billie Rinaldi commented on ACCUMULO-3742:
------------------------------------------

Mostly we are using PropertiesConfiguration to read a config file.  We could introduce a new constructor to ClientConfiguration that takes a config file and handles it properly (see below), although that would not prevent people from using it the broken way.
{noformat}
  public ClientConfiguration(String configFile) throws ConfigurationException {
    this(new PropertiesConfiguration(), configFile);
  }

  private ClientConfiguration(PropertiesConfiguration propertiesConfiguration, String configFile) throws ConfigurationException {
    super(propertiesConfiguration);
    // Don't do list interpolation
    propertiesConfiguration.setListDelimiter('\0');
    propertiesConfiguration.load(configFile);
  }
{noformat}

> When we use the pattern new ClientConfiguration(new PropertiesConfiguration), the PropertiesConfiguration has already interpreted any multi-valued properties as lists, so when we read those properties as strings we only get the first value in the list.  This affects instance.zookeeper.host and trace.span.receivers.
