> Key: HBASE-12270
> URL: https://issues.apache.org/jira/browse/HBASE-12270
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.11, 0.98.6.1
> Environment: I can reproduce it on a simple 2 node cluster, one
> running the master and another running a RS. I was testing on ec2.
> I used the following configurations for the cluster.
> hbase-env:HBASE_REGIONSERVER_OPTS=-Xmx2G -XX:MaxDirectMemorySize=5G
> -XX:CMSInitiatingOccupancyFraction=88 -XX:+AggressiveOpts -verbose:gc
> -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xlog
> gc:/tmp/hbase-regionserver-gc.log
> hbase-site:
> hbase.bucketcache.ioengine=offheap
> hbase.bucketcache.size=4196
> hbase.rs.cacheblocksonwrite=true
> hfile.block.index.cacheonwrite=true
> hfile.block.bloom.cacheonwrite=true
> Reporter: Khaled Elmeleegy
> Assignee: Liu Shaohui
> Priority: Critical
> Fix For: 2.0.0, 0.98.10, 1.1.0
>
> Attachments: HBASE-12270-v1.diff, TestHBase.java, TestKey.java

> In my experiments, I have writers streaming their output to HBase. The reader
> powers a web page and does this scatter/gather, where it reads 1000 keys
> written last and passes them the the front end. With this workload, I get the
> exception below at the region server. Again, I am using HBAse (0.98.6.1). Any
> help is appreciated.
