Difference in Rev ids Observed using CbTransfer in csv mode:: Active Data From Disk Vs Replica Data From Disk Vs Disk+Memory

Centos 64 bit, version 3.0.0-728, vbuckets=128

1. Create a 7 node cluster
2. Add 1 Default Bucket
3. Create 50K Documents
4. Add update mutaitons to 50% of documents
5. Wait for replicaiton to complete and disk queue to drain
6. Sleep for 60 seconds
7. Capture memory+disk, active data from disk, replica data from disk
8. Compare memory+disk Vs active, memory+disk Vs replica, active vs replica

In Step 8 data is not same for all comparisons, logs attached.

Since I am using CB Transfer assigning this bug to Bin. Once Bin confirms that cbtransfer working is correct, will assign this bug to Chiyoung.

note that we are using cbtransfer for data collection and then comparing

Will attach cbcollect logs soon.

Please use testrunner and this change:: http://review.couchbase.org/#/c/37529/ to run the following test

./testrunner -i ~/systest-worker/testrunner/palm.ini -t analysis.clusterinfoanalysis.DataAnalysisTests.test_data_analysis_disk_memory_comparison_all,items=50000,upr=True,vbuckets=128,replicas=1,force_kill_memcached=True
