Eric Newton commented on ACCUMULO-2057:
---------------------------------------
[[email protected]] the work around is to delete last locations, which is
safe. If your metadata table comes online, you should be able to do this in
the shell:
{noformat}
shell> grant -u root -t !METADATA Table.WRITE
shell> table !METADATA
shell> deletemany -f -c last
{noformat}
If your metadata table does not come up, you might be able to remove the
duplicate last locations from the root tablet like this:
{noformat}
shell> table !METADATA
shell> deletemany -f -c last -e !0<
{noformat}
Please seek help on the mailing list if you are not able to get your system up
and running.
