Yi Liu created HADOOP-11339: ------------------------------- Summary: 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
