astyanax - Why Cassandra throwing com.datastax.driver.core.exceptions.InvalidQueryException: Multiple definitions found for column - Stack Overflow

When the Java driver throws an InvalidQueryException, it's rethrowing an error from Cassandra. The error "Multiple definitions found for column..." indicates that a column is mentioned more than once in an update statement. You can simulate it in cqlsh:

cqlsh> create table test(i int primary key);  cqlsh> insert into test (i, i) values (1, 2);  code=2200 [Invalid query] message="Multiple definitions found for column i"  

I'm not familiar with Astyanax, but my guess is that it already adds the id to the query when you call withRow, so you don't need to add it again with putColumn. Try removing that call (second line in reformatted sample below):

m.withRow(cf, lb.getLbId())   .putColumn(LEADERBOARD_ID, UUIDUtil.asByteArray(lb.getLbId()), null)   ... // other putColumn calls
