How do I check if the Accumulo gc is running?  Can I force it to run?

I'm on version 1.5.

Is your GC running? It should be catching the unreferenced files.

I think you are safe to manually delete any files not references in the !METADATA table.

What version of Accumulo are you running?

I've run scan on hdfs under /accumulo/tables/<table_id> for all rfiles older than our
ageoff filter on that table.  When I then scan for these rfiles in the metadata table most
are not listed.

Should all rfiles be referenced in the metadata table?  My goal had been to get the rowid
from the metadata and then force a compaction on that range.  Eg for row   4n;234234234 file:/fdi-2342/234234<tel:2342%2F234234>.rf
   run a compaction for 234234234 to 234234234~

Thanks in advance.
