I've made a little experiment and recreated the table
with 'orc.create.index'='FALSE' and now it fails on something else:
Error: java.io.IOException:
org.apache.hadoop.hive.ql.metadata.HiveException:
java.lang.ClassCastException:
org.apache.hadoop.hive.ql.io.orc.ColumnStatisticsImpl$StringStatisticsImpl
cannot be cast to

It seems that the concatenation feature needs more work..
