> Reproduction needs an HDFS/Ozone cluster with at least R+1 data nodes where
> R=Replication factor.
> {code:java}
> drop table ice_t if exists;
> create table ice_t (i int, p int) partitioned by spec(p)
> stored as iceberg;
> insert into ice_t values (1,1);
> insert into ice_t values (2,1);
> insert into ice_t values (3,1);
> optimize table ice_t;
> show files in ice_t;
> refresh ice_t;
> describe history ice_t;
> select * from ice_t for system_version as of <earlier snapshot>;
> {code}
> The problem is that in IcebergScanPlanner.getFileDescriptor() we use
> getIceTable().getHostIndex() during time-travel which is an immutable object.
