need initClause when catch Exception and throw new Exception in cli
-------------------------------------------------------------------
Key: CASSANDRA-3312
URL: https://issues.apache.org/jira/browse/CASSANDRA-3312
Project: Cassandra
Issue Type: Bug
Reporter: Jackson Chung
Assignee: Pavel Yaskevich
Priority: Minor
through CASSANDRA-2746 , we added initCause to the Cli such that we could see
more meaningful exception stacktrace when certain exception is thrown.
However, there are still some other area, eg:
executeGetWithConditions(Tree)
executeSet(Tree)
executeIncr(Tree, long)
etc etc...
basically any time you do a
{code}
{
throw new RuntimeException(e.getMessage());
}
{code}
the real exception is lost. The right approach should be:
{code}
catch (Exception e)
{
throw new RuntimeException(e.getMessage(), e);
}
{code}
eg: i was getting this:
null
java.lang.RuntimeException
at
org.apache.cassandra.cli.CliClient.executeCLIStatement(CliClient.java:310)
at org.apache.cassandra.cli.CliMain.processStatement(CliMain.java:217)
at org.apache.cassandra.cli.CliMain.main(CliMain.java:345)

org.apache.cassandra.cli.CliClient.executeGetWithConditions(CliClient.java:815)
at
org.apache.cassandra.cli.CliClient.executeCLIStatement(CliClient.java:208)
... 2 more
but i have no idea what the problem is with just the above stack trace.
with the fix, this would tell us more:
null
