ENTRIES listed on accumulo 1.10 monitor
Good morning,
Just a quick question, what does the Entries on the accumulo master status page indicates for a table?
Yesterday i had to re-initialize accumulo 1.10, before starting i moved my hdfs /accumulo to /accumulo-old
then I copied rf files under /accumulo-old/tables/x to /tmp/x and after initializing i did directoryimport to create new table x
Everything worked flawlessly and hdfs data size /accumulo-old/table/x matches with /accumulo/table/x however, old Entries were 22B and new Entries are 2B
So what does the entries really represent? I always though it was actually a record count but doesn't appear that way..

On bulk import the count is not known. The count is updated on compactions. Once a tablet / file is compacted it's count will be updated. The count is only approximate anyway - it will not be able to determine of a row has expired (past age-off) after the count has been calculated.
