mck commented on CASSANDRA-13357:
---------------------------------
[~haozhong] and [~eduard.tudenhoefner],
taking another look at this, the patch was originally correct in only catching
an {{IllegalArgumentException}}…
The fix in CASSANDRA-8950 included changing {{StorageService}} so that it threw
an {{IllegalArgumentException}} instead of the {{NullPointerException}}.
See
https://github.com/apache/cassandra/commit/37eb2a0e29c22a1b2f033e8191b5808a6f7b0d3f#diff-b76a607445d53f18a98c9df14323c7dd
Looking in trunk, {{NodeTool}} already now handles the
{{IllegalArgumentException}}, printing it nicely to the user.
For example
{code}
nodetool getendpoints syste loca -7564491331177403445
nodetool: Unknown keyspace 'syste'
See 'nodetool help' or 'nodetool help <command>'.
{code}
If I apply the (originally) patch it changes this to…
{code}
bash build/dist/bin/nodetool getendpoints syste loca -7564491331177403445
Error: Unknown keyspace 'syste'
{code}
Given the code works fine as it is, I'm closing the issue as {{won't fix}}.
Feel free to comment or re-open if I got it wrong or missed anything.

> 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.
