we are running accumulo 1.9.3 yes; i dont know why they are zero length... there ended up only 10 or so rfiles; however i was able to org.apache.accumulo.core.file.rfile.CreateEmpty over top of those bad files after offline the table and then online it... life is good :-) it was only a dev table; however, i was concerned if this happened in prod...
the disks looked good and we have plenty of space; dont know what happened??? thanx On Wed, Sep 4, 2019 at 5:37 PM Christopher <[email protected]> wrote: > I can't match those line numbers up exactly.
