--------------------------------------
Summary: Handling AlterTableEvent operation in Automatic
Invalidate/Refresh of metadata should be invalidate rather than reload
Key: IMPALA-11813
URL: https://issues.apache.org/jira/browse/IMPALA-11813
Project: IMPALA
Issue Type: Bug
Components: Catalog
Affects Versions: Impala 4.1.1, Impala 4.2.0, Impala 4.1.0
Reporter: rongchuan.jin
As the
[docs|https://impala.apache.org/docs/build/html/topics/impala_metadata.html]
said, metastoreEventProcessor invalidates the tables when it receives the ALTER
TABLE event.
But in fact, we still use reloadTable to handle alterTableEvent, see in
[code|https://github.com/apache/impala/blob/branch-4.2.0/fe/src/main/java/org/apache/impala/catalog/events/MetastoreEvents.java#L1448]，which
is inconsistent and may leads to unexpected metastore sync thread shutdown.
