Subject Re: The schema definitions are not picked up....
Date Sun, 09 May 2010 03:49:52 GMT
Hi Brandon and Jonathan,

Thank you for the help! The keyspace was created successfully! Another issue
emerged: Does client.get_range_slices(...) work in the trunk?

Here is my code;

ColumnParent cp = new ColumnParent("CF1");

 // read entire columns of the CF

SlicePredicate predicate = new SlicePredicate();

SliceRange sliceRange = new SliceRange();

sliceRange.setStart(new byte[0]);

sliceRange.setFinish(new byte[0]);

predicate.setSlice_range(sliceRange);

 KeyRange range = new KeyRange(10);

range.setStart_key("".getBytes());

range.setEnd_key("".getBytes());

 client.set_keyspace(keyspace);

List<KeySlice> slices = client.get_range_slices(cp, predicate, range,
ConsistencyLevel.ONE);

It ended up with error messages such as java.io.EOFException. Some snippets
below. Any idea how to fix it?
