------------------------------------
Summary: Key constructor, Column Visibility can corrupt a table
Key: ACCUMULO-651
URL: https://issues.apache.org/jira/browse/ACCUMULO-651
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.4.0
Environment: RHEL 6, Hadoop 0.20.2, ZooKeeper 3.4.3, Accumulo 1.4.0
Reporter: Bob Thorman
Assignee: Keith Turner
Priority: Minor
The Key constructor does not check the integrity of the column visibility field
which can cause some corruption in a table. For example the following code
will generate a valid Key that can be written to a table
Key k = new Key(new Text("BOB"), new Text("CF"), new Text("CQ"), new
Text("public,private"), System.currentTimeMillis());
and that key can be used as output (in my case a mapreduce job).
During scan operations the following exception is thrown...
