> Reduce Connection and RpcClient creations in unit tests

> Key: HBASE-13097
> URL: https://issues.apache.org/jira/browse/HBASE-13097
> Project: HBase
> Issue Type: Bug
> Components: IPC/RPC, test
> Affects Versions: 2.0.0, 1.1.0
> Reporter: zhangduo
> Assignee: zhangduo
> Fix For: 2.0.0, 1.1.0
>
> Attachments: HBASE-13097.patch
>
>
> In some unit tests(such as TestAcidGuarantees) we create multiple Connection
> instance. If we use AsyncRpcClient, then there will be multiple netty
> Bootstrap and every Bootstrap has its own PooledByteBufAllocator.
> I haven't read the code clearly but it uses some threadlocal technics and
> jmap shows io.netty.buffer.PoolThreadCache$MemoryRegionCache$Entry is the
> biggest things on Heap.
> See

> 2015-02-24 23:50:29,704 WARN [JvmPauseMonitor]
> util.JvmPauseMonitor$Monitor(167): Detected pause in JVM or host machine (eg
> GC): pause of approximately 20133ms
> GC pool 'PS MarkSweep' had collection(s): count=15 time=55525ms
> {noformat}
> Update: We use a singleton PooledByteBufAllocator so the reason should be too
> many threads. So we will work on reduce the connections and rpclients in unit
> tests.
