Hi Dave,
In general you shouldn't need to create the data store directly.
Instead, use the DataStoreFinder with a map of input parameters.
These parameters haven't changed, and are generally more stable.
The bare minimum needed is shown here, with more advanced options
directly below:

Thanks,
Emilio

All:
Trying to refactor some code to work with GeoMesa 1.3.0
(or newer). There
were changes in how one set up an AccumuloDataStoreConfig and
AccumuloDataStore
(a lot of the parameters moved around).
What has me completely stumped (due most likely to my weak
Java Foo) is the parameter
to the AccumuloDataStoreConfig for the audit option
implementations to audit queries.
NOTE - Don't want to audit queries so a null should be
allowed to work here but it doesn't.
I get a scala.MatchError: (null,None) (of class scala.Tuple2)
In any case I can't get the syntax for the
Option<Tuple3<AuditWriter, AuditProvider, String>>
to
work. I can't find an example of other than a MockAuditWriter
in the Scala unit tests. What class
needs to be instantiated for that portion of the options?
I have tried instantiating a Some object for the Tuple but
can't seem to find the correct incantation for
that.
More Java examples of these things would be very helpful.
Below is my code (does not compile), any help would be
appreciated.
AuthorizationsProvider
authProvider = new DefaultAuthorizationsProvider();
AuditProvider auditProvider = new
ParamsAuditProvider();
AuditWriter auditWriter = new AuditWriter();
Option<Tuple3<AuditWriter,
AuditProvider, String>> auditOptions =
{{ auditWriter, auditProvider, ""}};
String defaultVisibilities = "";
Option<Object> queryTimeout = new
Some<Object>(2000l);
int queryThreads = 1;
int recordThreads = 1;
int writeThreads = 1;
boolean generateStats = false;
boolean collectUsageStats = false;
boolean caching = false;
boolean looseBBox = false;
/**

AccumuloDataStoreConfig(coalesceSearchTable,
