----------------------------------------
Summary: droptable crated infinite METADATA scan loop
Key: ACCUMULO-2361
URL: https://issues.apache.org/jira/browse/ACCUMULO-2361
Project: Accumulo
Issue Type: Bug
Affects Versions: 1.5.0
Reporter: Chris McCubbin
Working with [~vines] on this one...
Setup: Created a couple tables, added some data, then dropped them. The drop
hangs and !METADATA (which has ~400 entries) is scanned in what looks like an
infinite loop.
The table being dropped loks like this in !METADATA:
{code}
root@sqrrl> scan -b 3 -e 5 -t !METADATA
4;\x00\x00\x06f srv:dir [] /t-00000b6
4;\x00\x00\x06f srv:lock []

We think this may be the relevant message in the master debug logs:

...etc
{code}
Graceful accumulo reboot hangs.
Hard reboot of everything (control-c'd) clears the problem.
