In older Hive versions (0.10 and earlier) no distinction was made between partition columns or non-partition columns while displaying columns in DESCRIBE TABLE. From version 0.12 onwards, they are displayed separately. This flag will let you get the old behavior, if desired. See test-case in patch for HIVE-6689.

hive.metastore.limit.partition.request
  • Default value: -1
  • Added In: Hive 2.2.0 with HIVE-13884

This limits the number of partitions that can be requested from the Metastore for a given table. A query will not be executed if it attempts to fetch more partitions per table than the limit configured. A value of "-1" means unlimited. This parameter is preferred over hive.limit.query.max.table.partition (deprecated).

hive.limit.query.max.table.partition
  • Default Value: -1
  • Added In: Hive 0.13.0 with HIVE-6492
  • Deprecated In: Hive 2.2.0 with HIVE-13884 (See hive.metastore.limit.partition.request)

To protect the cluster, this controls how many partitions can be scanned for each partitioned table. The default value "-1" means no limit. The limit on partitions does not affect metadata-only queries.
