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.
