Keith Turner created ACCUMULO-2520:
--------------------------------------

             Summary: Garbage collector deleted everything when given bad input
                 Key: ACCUMULO-2520
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2520
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.4.0
            Reporter: Keith Turner
            Priority: Critical
             Fix For: 1.4.5, 1.5.2, 1.6.0


Patch v3 of the upgrade from ACCUMULO-2145 had a test that did the following before upgrade.

{noformat}
root@testUp> table !METADATA
root@testUp !METADATA> grant Table.WRITE -u root 
root@testUp !METADATA> insert ~del testDel test valueTest
{noformat}

This is a malformed delete entry.  Accumulo code should not delete such entries.  When the
1.5.1 garbage collector saw this it did the following.

{noformat}
2014-03-20 18:20:05,359 [gc.SimpleGarbageCollector] DEBUG: Deleting /accumuloTest/tables
2014-03-20 18:20:05,359 [gc.SimpleGarbageCollector] DEBUG: Deleting /accumuloTest/tables/!0/default_tablet/F0000009.rf
2014-03-20 18:20:05,360 [gc.SimpleGarbageCollector] DEBUG: Deleting /accumuloTest/tables/!0/table_info/F000000b.rf
{noformat}

GC should validate that delete entries are paths of the expected length.  I have confirmed
this bug exist in 1.5.1.  I am assuming it exist in 1.4 and 1.6 branches.
