> Key: IMPALA-6385
> URL: https://issues.apache.org/jira/browse/IMPALA-6385
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Reporter: Adam Holley
> Priority: Minor
>
> In CatalogOpExecutor, several of the alter statements have inconsistent
> behavior. For example, if passing partition parameters, after some alter
> statements, the metadata for the partition is just marked dirty and will be
> reloaded on the next read. If not using partition parameters, the table
> metadata and default partition metadata is reloaded. Specifically, in
> alterTableSetFileFormat, if the partitionSet is null, the method will return
> true which results in HdfsTable.load being called with
> loadPartitionFileMetadata true which reloads the metadata. However if the
> partitionSet is not null, the metadata is not reloaded and instead the
> partition is instead just marked dirty
> (catalog_.getHdfsPartition(...).markDirty()).
