Change subject: IMPALA-10504: Add tracing for remote block reads ...................................................................... IMPALA-10504: Add tracing for remote block reads This patch logs metadata for the first unexpected remote read of each scanrange when the flag fs_trace_remote_reads is set to true. This logging is intended to help diagnose the root cause of remote reads. Since a message may be logged for each scan range, there could be several hundred lines of output in a degenerate case. However, the remote read condition is not expected and verbose output may be needed to diagnose the root cause.
