Andrew Purtell commented on HBASE-10643:
----------------------------------------
Did not encounter this issue when testing recently with bucket cache using the
direct buffer ioengine and MaxDirectMemorySize of 24g and 32g. Can you share
your JVM version particulars, command line options you might have put in
hbase-env.sh, and have you changed any of the HBase site file settings
pertaining to zookeeper?
> 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.
