Change subject: [BLOCKED][KUDU-3342] Add an implementation of the block cache on HBW ...................................................................... [BLOCKED][KUDU-3342] Add an implementation of the block cache on HBW Blocked by https://gerrit.cloudera.org/#/c/19726/ This commit adds support for a high bandwidth memory cache based on hbwmalloc[1]. The cache is configured using a new flag --block_cache_type=HBW. For testing purposes, the new cache implementation wil be run on DRAM by calling hbw_set_policy() with HBW_POLICY_PREFERRED though there is not likely to be a performance advantage. The code changes contained are: * introduce the new flags to select the cache implementation * introduce the new cache implementation, which uses hbwmalloc APIs to allocate/free memory * cfile-test and block_cache-test are made into value-parameterized tests and test with all three cache types.
