Duo Zhang commented on HBASE-27919:
-----------------------------------
Checked the log output, the sum of UNDEF and UNREF counters are both 7564,
which indicates that we lost 7564 rows.
And I also checked the Extras on ref without a def log line, the lost keys are
across all the regions, and among the 4 mappers, 3 mappers have lost rows while
1 mapper has not.
So it is more likely to be a client side issue, where in the 3 mappers we
failed to write some rows but we did not fail the job.
We use BufferedMutator in ITBLL, let me dig more.
Thanks.
