[BUG] FE restart failed when replaying alter job

[gengjun-git]

Steps to reproduce the behavior (Required)

1. create a table

CREATE TABLE aggregate_table_with_null (k1 decimal(7,2),k2 int,k3 decimal(30,17),v1 int sum,v2 int min,v3 int max) AGGREGATE KEY (k1, k2, k3) DISTRIBUTED BY HASH(k1, k2, k3) BUCKETS 32 PROPERTIES ( "replication_num" = "3", "in_memory" = "false", "storage_format" = "V2" );

2. create a mv on that table

create materialized view aggregate_table_with_null_mv as select k1, sum(v1), min(v2), max(v3) from aggregate_table_with_null group by k1;

3. restart FE immediately after step 2.

4. wait for the completion of the alter job.

5. restart FE.

Expected behavior (Required)

step 5 should succeed.
