Csaba Ringhofer commented on IMPALA-9164:
-----------------------------------------
This seemed very simple at first, as the whole data load logic runs in a java
function in the coordinator. LOAD DATA cannot create new partitions, so HMS was
not touched at all, unlike insert.
What makes this more complicated for ACID tables is COLUMN_STATS_ACCURATE -
this has to be removed during an alter table, so we'll have to call from
coordinator to catalogd, which will call alter_table in HMS.
