--------------------------------
Summary: libhdfs++: potential segfault after teardown
Key: HDFS-9687
URL: https://issues.apache.org/jira/browse/HDFS-9687
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Bob Hansen
Assignee: Bob Hansen
During shutdown, it is possible for an RPC task to outlive the RPC connection
and segfault when it attempts to signal the engine on timeout.
In rpc_connection.h, the callback
{code}
req->timer().async_wait(std::bind(
&RpcConnection::HandleRpcTimeout, this, req, _1));
{code}
does not retain a reference to shared_this, so the connection can be destroyed.
