--------------------------------------
Summary: libhdfs++: SASL events should be scoped closer to usage
Key: HDFS-11767
URL: https://issues.apache.org/jira/browse/HDFS-11767
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: James Clampffer
Assignee: James Clampffer
"SASL Start" and "SASL End" are called in the SaslProtocol constructor and
destructor. SaslProtocol is held by a shared_ptr so there's a race where the
RpcConnection can be torn down and another can be put in it's place while a
callback is still holding the shared_ptr preventing "SASL End" from being
called.
This can matter a lot because both Cyrus SASL and gsasl aren't thread safe
during negotiation. These event hooks provide a mechanism to pick up a process
wide lock that guards access to the sasl library.
