[~daryn], any updates? Thanks
> Reuse buffer for Hadoop RPC
> ---------------------------
>
> Key: HADOOP-11339
> URL: https://issues.apache.org/jira/browse/HADOOP-11339
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ipc, performance
> Reporter: Yi Liu
> Assignee: Yi Liu
>
> For Hadoop RPCs, we will try to reuse the available connections.
> But when we process each rpc in the same connection, we will allocate a fresh
> heap byte buffer to store the rpc bytes data. The rpc message may be very
> large, i.e., datanode blocks report.
> There is chance to cause full gc as discussed in HDFS-7435
