> When executing a statement from the cassandra-cli (with --debug) , if an
> exception is thrown from one of the cases in side the executeCLIStatement
> method, the root cause is swallowed. For specific case such as the
> InvalidRequestException or the SchemaDisagreementException, just the message
> itself maybe enough, but for the general Exception case, without the root
> cause, it could be difficult to debug the issue.
> For example, we have seen exception like:
> {noformat}
> null
> java.lang.RuntimeException
> at org.apache.cassandra.cli.CliClient.executeCLIStatement(CliClient.java:209)
> at org.apache.cassandra.cli.CliMain.processStatement(CliMain.java:223)
> at org.apache.cassandra.cli.CliMain.main(CliMain.java:351)
> {noformat}
> the null there would most likely indicate this is a NPE (though it could
> still be any Exception with null message). By adding a initCause to the
> caught exception, we could see the root cause, eg:
> {noformat}
> null
> java.lang.RuntimeException
> at
> org.apache.cassandra.cli.CliClient.executeCLIStatement(CliClient.java:212)
> at org.apache.cassandra.cli.CliMain.processStatement(CliMain.java:223)
> at org.apache.cassandra.cli.CliMain.main(CliMain.java:351)
> Caused by: java.lang.NullPointerException
> at
> org.apache.cassandra.cli.CliClient.describeKeySpace(CliClient.java:1336)
> at
> org.apache.cassandra.cli.CliClient.executeShowKeySpaces(CliClient.java:1166)
> at
> org.apache.cassandra.cli.CliClient.executeCLIStatement(CliClient.java:170)
> ... 2 more
> {noformat}
> submitting a patch here that would add the initCause to all caught exceptions
> here. But the most important one is the general Exception case.
