mck updated CASSANDRA-13357:
----------------------------
Reviewers: Eduard Tudenhoefner, mck
Status: Review In Progress (was: Patch Available)
> A possible NPE in nodetool getendpoints
> ---------------------------------------
>
> Key: CASSANDRA-13357
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13357
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/nodetool
> Reporter: Hao Zhong
> Assignee: Hao Zhong
> Priority: Normal
> Fix For: 4.x
>
> Attachments: cassandra.patch
>
>
> The GetEndpoints.execute method has the following code:
> {code:title=GetEndpoints.java|borderStyle=solid}
> List<InetAddress> endpoints = probe.getEndpoints(ks, table, key);
> for (InetAddress endpoint : endpoints)
> {
> System.out.println(endpoint.getHostAddress());
> }
> {code}
> This code can throw NPE. A similar bug is fixed in CASSANDRA-8950. The buggy
> code is
> {code:title=NodeCmd.java|borderStyle=solid}
> List<InetAddress> endpoints = this.probe.getEndpoints(keySpace, cf, key);
> for (InetAddress anEndpoint : endpoints)
> {
> output.println(anEndpoint.getHostAddress());
> }
> {code}
> The fixed code is:
> {code:title=NodeCmd.java|borderStyle=solid}
> try
> {
> List<InetAddress> endpoints = probe.getEndpoints(keySpace, cf,
> key);
> for (InetAddress anEndpoint : endpoints)
> output.println(anEndpoint.getHostAddress());
> }
> catch (IllegalArgumentException ex)
> {
> output.println(ex.getMessage());
> probe.failed();
> }
> {code}
> The GetEndpoints.execute method shall be modified as CASSANDRA-8950 does.
