Hi, Josh, Thanks for responding so quickly... sorry, I should've mentioned that I'm running Accumulo 1.5.0.

It just interleaves the 2 errors above from the state.MetaDataTableScanner and util.TabletIterator loggers. -Russ On Wed, Feb 26, 2014 at 8:37 PM, Josh Elser <[email protected]> wrote: > Hi Russ, > > What version of Accumulo are you running? > > Any other exceptions in the Monitor? > > - Josh > > > On 2/26/14, 11:10 PM, Russ Weeks wrote: > >> Hi, All, >> >> I can't delete any tables through the accumulo shell, I keep getting the >> message: "Internal error processing waitForTableOperation". >> >> Recently my accumulo cluster has started showing this error repeatedly >> in the master log: >> [state.MetaDataTableScanner] WARN : No prev-row for key extent: {z< : [] >> 9223372036854775807 >> false= loc243f8e8ad6f5875>. 10.128.1.17:9997 ~tab ~pr-� �} >> >> And this error in the monitor log: >> [util.TabletIterator] WARN : gc:agile01 Metadata problem : tablet !0;!0< >> has no prev end row >> >> And this in the GC log: >> [util.TabletIterator] WARN : Metadata problem : tablet !0;!0< has no >> prev end row >> [util.TabletIterator] INFO : Resetting !METADATA scanner to [!0 : [] >> 9223372036854775807 false,~ : [] 9223372036854775807 false) >> >> Maybe coincidence, but it seems like things started getting weird when I >> added a WholeRowIterator through the accumulo shell (which is nonsense, >> I know).
