Hi,
I'm trying to use arrow flight and keep getting this exception below when
calling flightClient.getStream() - java.lang.NoClassDefFoundError: Could not
initialize class org.apache.arrow.memory.util.MemoryUtil
It's quite odd because I have arrow-memory-core defined in my pom. I'm using
v8.0.0. Any ideas what this could be? I'm running this in IntelliJ.
Code:
try (var allocator = new RootAllocator(); var flightClient =
FlightClient.builder(allocator, location).build()) {
var flightStream = flightClient.getStream(ticket);
if (flightStream.next()) {
retval = flightStream.getRoot();
}
}
