> When RS is brought up with XX:MaxDirectMemorySize of 22GB or higher, RS fails after a
successful start. From the RS logs it looks like the bucketCache memory allocation is taking
more time makes the RS considered dead by ZK. One option to fix the problem would be to allocate
the bucketCache before registering with ZK.
