--------------------------------------
[~gsbiju] This was running in EC2, no?
> Failure in RS when using large size bucketcache
> -----------------------------------------------
>
> Key: HBASE-10643
> URL: https://issues.apache.org/jira/browse/HBASE-10643
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 0.98.0, 0.96.0
> Reporter: Biju Nair
> Labels: bucketCache, regionserver
>
> 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.
