Hive metastore listener port.

hive.metastore.

...

• Default Value: 1
• Added In: Hive 2.1.0 with HIVE-12075

Number of threads to use to read file metadata in background to cache it.

hive.metastore.initial.metadata.count.enabled 

...

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.metastore.fastpath

• Default Value: false
• Added In: Hive 2.0.0 with HIVE-9453

Used to avoid all of the proxies and object copies in the metastore. Note, if this is set, you MUST use a local metastore (hive.metastore.uris must be empty) otherwise undefined and most likely undesired behavior will result.

hive.metastore.hbase.cache.size

• Default Value: 100000
• Added In: Hive 2.0.0 with HIVE-9453

• Default Value: 600s
• Added In: Hive 2.0.0 with HIVE-9453

Number of seconds for stats items to live in the cache.

hive.metastore.hbase.file.metadata.threads
