Sean Busbey created ACCUMULO-4444:
-------------------------------------
Summary: NullPointerException when password not given to
TraceTableStats
Key: ACCUMULO-4444
URL: https://issues.apache.org/jira/browse/ACCUMULO-4444
Project: Accumulo
Issue Type: Bug
Components: trace
Affects Versions: 1.7.2
Environment: 1.7.2 cluster
Reporter: Sean Busbey
Priority: Critical
I'm trying to follow the [admin guide on
tracing|https://accumulo.apache.org/1.7/accumulo_user_manual#_viewing_collected_traces],
specifically with the {{TraceTableStats}} command.
In attempting to get prompted for the password, I provided a username and no
password, which resulted in a NullPointerException.

The impacted line is checking to see if the credential has expired, without
checking to see if there is a credential in the first place, I think?
{code}
57 public ConnectorImpl(final ClientContext context) throws AccumuloException,
AccumuloSecurityException {
58 checkArgument(context != null, "context is null");
59 if (context.getCredentials().getToken().isDestroyed())
60 throw new
AccumuloSecurityException(context.getCredentials().getPrincipal(),
SecurityErrorCode.TOKEN_EXPIRED);
{code}
