Good day
I have a problem connecting the presto driver

%%classpath add mvn
com.facebook.presto presto-base-jdbc 0.232
%defaultDatasource jdbc:presto://root@127.0.0.1:8282/hive/default

I can not figure it out and I can not see the full error trace.

I started using spotless in a maven java project for the first time. I am getting an exception indicating that there are unused imports. I can strip down the file to be as simple as

package example;
public interface Test {
}

There are no imports at all, but still there is the removeUnusedImports error.

It could be great to have a placeholder that represents the current uptime of application, e.g. {uptime}. The init time may be the same as the logger initialization time.

Even if you don't like this proposal, it might be solved by the posiblity of being able to register custom placeholder.

The current search() implementation performs a case-sensitive match. We should add a flag to the search call to make it case insensitive, i.e.,

def search(query: String, caseInsensitive: Boolean = false): RDD[Long]

For a query string abc, it would be equivalent to executing the following regular expression query:

[aA][bB][cC]
