Quanlong Huang commented on IMPALA-13009:
-----------------------------------------
Still finding a determined way to reproduce this. Currently using the following
script:
{code:bash}
impala-shell.sh -B --quiet -q "create table if not exists my_part(i int)
partitioned by (p int); insert into my_part partition(p) values
(1,1),(2,2),(3,3)"
i=1
while true; do
beeline -u "jdbc:hive2://localhost:11050" -e "alter table my_part drop
partition(p>0)"
hdfs dfs -rm -R -skipTrash hdfs://localhost:20500/test-warehouse/my_part
impala-shell.sh -B --quiet --ignore_query_failure -q "alter table my_part
recover partitions; invalidate metadata my_part; show partitions my_part"
sleep 1
i=$((i+3))
impala-shell.sh -B --quiet -q "insert into my_part partition(p) values
($i,$i),($((i+1)),$((i+1))),($((i+2)),$((i+2)))"
done{code}
I can only reproduce it 4 times in a whole day.

> Key: IMPALA-13009
> URL: https://issues.apache.org/jira/browse/IMPALA-13009
> Project: IMPALA
> Issue Type: Bug
> Components: Catalog
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Critical
>
> Catalogd might not send partition deletions to the catalog topic in the
> following scenario:
> * Partitions of a table are dropped externally outside Impala.
> * Table dir is also removed on HDFS.
> * ALTER TABLE RECOVER PARTITIONS failed by FileNotFoundException on the table
> dir.
> * A subsequent INVALIDATE METADATA on the same table succeeds to invalidated
> the table.
> After the INVALIDATE finishes, catalogd might not send deletions of the
> dropped partitions to the catalog topic. Then the catalog topic only have the
> updates of those partitions, no deletions.
> This will be detected when a coordinator restarts:
