Hi Josh, > Versions of Hadoop and Accumulo: Hadoop 1.2.1 Accumulo 1.6.1 > Are the accumulo.metadata/!METADATA and/or accumulo.root tables online? Nope.. I tried to scan the tables -- it just hangs > Have you checked the logs of the Master and/or TabletServer for any exceptions? The master log is locked for read operation (an info message). I tried to shutdown the master with accumulo admin -f stopMaster, but it's still unhappy. The tserver log doesn't have any exceptions. However, if I run accumulo tserver -a localhost, then I'll get a "Could not create ServerSocket.." error as it can't connect to the tserver.
For more context, I ran into all of this because I'm running this on a vm and I ran out of disk space so Accumulo could no longer write to the wal reliably and then checksums weren't matching up. After I created more space on my vm, I deleted the wal logs, hoping that it would revert to what was in /accumulo/tables, but then ran into this error where I have zero tablets. Thanks for any suggestions on what to do next! - Kina On Tue, Feb 24, 2015 at 11:13 AM, Josh Elser <[email protected]> wrote: > Hi Kina, > > Can you share some more information? > > * Versions of Hadoop and Accumulo > * Are the accumulo.metadata/!METADATA and/or accumulo.root tables online? > * Have you checked the logs of the Master and/or TabletServer for any > exceptions? > > - Josh > > Kina Winoto wrote: > >> Hi, >> >> I'm running a local instance of accumulo with just one tablet server.
