http://gerrit.cloudera.org:8080/#/c/6498/6/be/src/runtime/bufferpool/buffer-pool-test.cc
File be/src/runtime/bufferpool/buffer-pool-test.cc:

PS6, Line 1434: flushing heuristic does not eagerly start writes when there are no
              :   // disks.
which path in WriteDirtyPagesAsync() is this?


Line 1479:   IMPALA_ASSERT_DEBUG_DEATH(pool->Unpin(&client, &pages[0]), "");
just to confirm, this is the DCHECK_EQ(0, dirty_unpinned_bytes_); in WriteDirtyPagesAsync()?

File be/src/runtime/tmp-file-mgr.cc:

PS5, Line 274: tus err_status(TErrorCode::SCRATCH_ALLOCATION_FAILED);
             :     for (Status& err : scratch_errors_) err_status.Merg
isn't that still the case? will we want to update this message still when 4697 is addressed?

File be/src/runtime/tmp-file-mgr.cc:

Line 358:   LOG(INFO) << "Allocated in " << tmp_file->path();
did you mean to keep this?
