Michael Ho has uploaded a new patch set (#3). Change subject: IMPALA-4180: Synchronize accesses to RuntimeState::reader_contexts_ ......................................................................
IMPALA-4180: Synchronize accesses to RuntimeState::reader_contexts_ HdfsScanNodeBase::Close() may add its outstanding DiskIO context to RuntimeState::reader_contexts_ to be unregistered later when the fragment is closed. In a plan fragment with multiple HDFS scan nodes, it's possible for HdfsScanNodeBase::Close() to be called concurrently. To allow safe concurrent accesses, this change adds a SpinLock to synchronize accesses to 'reader_contexts_' in RuntimeState.
