You set which via the hbase.bucketcache.ioengine setting.Setting it to offheap will have BucketCache make its allocations off-heap, and an ioengine setting of file:PATH_TO_FILE will direct BucketCache to use file caching (Useful in particular if you have some fast I/O attached to the box such as SSDs). From 2.0.0, it is possible to have more than one file backing the BucketCache. This is very useful especially when the Cache size requirement is high. For multiple backing files, configure ioengine as files:PATH_TO_FILE1,PATH_TO_FILE2,PATH_TO_FILE3. BucketCache can be configured to use an mmapped file also. Configure ioengine as mmap:PATH_TO_FILE for this.
