Fix iceberg catalog bug This PR #30198 change the logic of `IcebergHMSExternalCatalog.java`, to get locationUrl by calling hive metastore's `getCatalog()` method. But this method only exists in hive 3+. So it will fail if we using hive 2.x. I temporary remove this logic, because this logic is only used from iceberg table writing. Which is still under development. We will rethink this logic later. 2. Fix test cases Some of P2 test cases missed `order_qt`. And because the output format of the floating point type is changed, some result in `out` files need to be regenerated. * [revert](jni) revert part of #32455 (#32904) * [fix](spill) Avoid releasing resources while spill tasks are executing (#32783) * [chore](log) print query id before logging profile in be.INFO (#32922) * [fix](grace-exit) Stop incorrectly of reportwork cause heap use after free #32929 * [improvement](decommission be) decommission check replica num (#32748) * [fix](arrow-flight) Fix reach limit of connections error (#32911) Fix Reach limit of connections error in fe.conf , arrow_flight_token_cache_size is mandatory less than qe_max_connection/2. arrow flight sql is a stateless protocol, connection is usually not actively disconnected, bearer token is evict from the cache will unregister ConnectContext.

Sometimes, one column may store a very long text value, collecting NDV for that column may use too much memory and may cause BE OOM. This pr is to limit the max string length to 1024 while collecting column stats to control BE memory usage.
