Change subject: Limit number of rowsets in compaction selection to 32 in TSAN mode ...................................................................... Limit number of rowsets in compaction selection to 32 in TSAN mode TSAN limits the number of simultaneous lock acquisitions in a single thread to 64 when using the deadlock detector[1]. However, compaction can select up to 128 (128MB budget / 1MB min rowset size) rowsets in a single op. kudu-tool-test's TestNonRandomWorkloadLoadgen almost always hits TSAN's limit when the KUDU-1400 changes following this patch are applied. This patch prevents this by limiting the number of rowsets selected for a compaction to 32 when running under TSAN. I ran the test with the KUDU-1400 changes on top and saw 97/100 failures. With the change, I saw 100 successes.
