Peter Vary updated HIVE-19718:
------------------------------
Status: Patch Available (was: Open)
> Adding partitions in bulk also fetches table for each partition
> ---------------------------------------------------------------
>
> Key: HIVE-19718
> URL: https://issues.apache.org/jira/browse/HIVE-19718
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 3.0.0
> Environment: Looking at {{convertToMPart}}:
> {code:Java}
> private MPartition convertToMPart(Partition part, boolean useTableCD)
> throws InvalidObjectException, MetaException {
> MTable mt = getMTable(part.getCatName(), part.getDbName(),
> part.getTableName());
> ...
> {code}
> So what we have as a result is that we fetch table for every partition where
> it should be done just once.
> Reporter: Alexander Kolbasov
> Assignee: Peter Vary
> Priority: Major
> Attachments: HIVE-19718.patch

>
> The ObjectStore.addPartitions() method does this:
> {code:java}
> for (Partition part : parts) {
> if (!part.getTableName().equals(tblName) ||
> !part.getDbName().equals(dbName)) {
> throw new MetaException("Partition does not belong to target table "
> + dbName + "." + tblName + ": " + part);
> }
> MPartition mpart = convertToMPart(part, true); // <-- Here
> toPersist.add(mpart);
> ...{code}
