--------------------------------------
Summary: libhdfs++: Something is holding connection_state_lock in
RpcConnectionImpl destructor
Key: HDFS-10409
URL: https://issues.apache.org/jira/browse/HDFS-10409
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: James Clampffer
The destructor to RpcConnectionImpl grabs a lock using a std::lock_guard<>.
It turns out something is already holding the lock when this happens. Best bet
is something that looks like:
{code}
void SomeFunctionThatShouldntTakeLock(){
std::lock_guard<std::mutex> bad(connection_state_lock_)
conn_.reset(); //conn is a shared_ptr to RpcConnectionImpl
}
{code}
