Based on my understanding, the solution of FB team is to retry the
following commands multiple times:
```
getPartitionsByFilterMethod.invoke(hive, table,
filter).asInstanceOf[JArrayList[Partition]]
```
This really depends on what is the actual errors that fail
`getPartitionsByFilterMethod`. When there are many concurrent users share the
same metastore, `exponential backoff with retries` is very reasonable since
most of errors might be caused by timeout or similar reasons.
If it still fails, I would suggest to fail fast or depends on the conf
value of `spark.sql.hive.metastorePartitionPruning.fallback.enabled`
