Test case for HBASE-22127 in LruBlockCache.

Throws:

public void testReaderWithCombinedBlockCache()
                                      throws Exception

Test case for HBASE-22127 in CombinedBlockCache

Throws:

testReaderBlockAllocationWithLRUCache

public void testReaderBlockAllocationWithLRUCache()
                                           throws IOException

Tests that we properly allocate from the off-heap or on-heap when LRUCache is configured. In this case, the determining factor is whether we end up caching the block or not. So the below test cases try different permutations of enabling/disabling via CacheConfig and via user request (cacheblocks), along with different expected block types.

Throws:

IOException

testReaderBlockAllocationWithLRUCache

private void testReaderBlockAllocationWithLRUCache(boolean cacheConfigCacheBlockOnRead,
 boolean cacheBlock,

Tests that we properly allocate from the off-heap or on-heap when CombinedCache is configured. In this case, we should always use off-heap unless the block is an INDEX (which always goes to L1 cache which is on-heap)

Throws:

IOException
