Quanlong Huang updated IMPALA-11402:
------------------------------------
Epic Link: IMPALA-13782
> getPartialCatalogObject fails with OOM with huge number of partitions
> ---------------------------------------------------------------------
>
> Key: IMPALA-11402
> URL: https://issues.apache.org/jira/browse/IMPALA-11402
> Project: IMPALA
> Issue Type: Bug
> Components: Catalog
> Reporter: Quanlong Huang
> Assignee: Quanlong Huang
> Priority: Critical
>
> The response size of getPartialCatalogObject depends on the number of
> partitions in the request. Even with the optimization of IMPALA-7501, the
> response size could still exceeds the 2GB byte array limit if requesting all
> partitions of a huge table.
> We should add flag to limit the number of partitions in a single
> getPartialCatalogObject request. When more partitions are required, fetch
> them in different batches.
