Hive Configuration Properties

...

• Default Value: false
• Added In:

Use a level 2 cache. Turn this off if metadata is changed independently of Hive metastore serverThis parameter does nothing. Warning note : For most installations, Hive should not enable the DataNucleus L2 cache, since this can causes correctness issues. Thus, some people set this parameter to false assuming that this disables the cache – unfortunately, it does not. To actually disable the cache, people should set "datanucleus.cache.level2.type" to "none".

datanucleus.cache.level2.type

• Default Value: SOFTnone
• Added In:

NONE=disables datanucleus l2 cache, SOFT=soft reference based cache, WEAK=weak reference based cache. Warning note : For most hive installations, enabling datanucleus cache can lead to correctness issues, and is dangerous to turn on. This should be left  as "none".
