Some tips from Ed:
The key is what shows up in the metadata - if you look at the System Metadata
tables section in the Accumulo user’s manual, the files entries have a form of
row_id, filename, file_size, row_count.
The monitor is reflecting what the the metadata table is showing. In the case
of a bulk import, there will not be a row count estimate, so it will not show
in the monitor.
If you entered a row via the shell and then did a flush (or a flush occurred
for any reason) that will create a file entry that includes the row estimate,
soi it will show up in the monitor.
If you perform a full compaction (compact -w -t <TABLENAME>), when it
finishes, all of the rows will have been processed and written to “new” files, and
those file entries will contain the row count values and should show up in the
monitor.
Overall, the value shown in the monitor is a estimate and may or may not
reflect the number of rows available in a table via a scan (things like TTL,
bulk imports, values written to memory but not flushed to a file)… Right after
a compaction, the value should be close, but again, just an estimate.

Thanks Mike,
If my bulk inserted data with visibility labels is not showing up (but a
ne=
wly inserted row from the shell does show up on monitor). All the data
show=

--dump=
shows everything nicely.
This is happening consistently, so trying understand how it works and how

an I diagnose this?
Thanks in advance
