Hello Aman Sinha, Joe McDonnell, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#6).
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.
