[jira] [Created] (HBASE-23204) Increase readability of any Java exceptions thrown in hbase shell

Richard Wise created HBASE-23204:
------------------------------------

             Summary: Increase readability of any Java exceptions thrown in hbase shell
                 Key: HBASE-23204
                 URL: https://issues.apache.org/jira/browse/HBASE-23204
             Project: HBase
          Issue Type: Improvement
          Components: shell
    Affects Versions: 1.2.0
         Environment: Windows 7, HBase 1.2.0-cdh5.16.1
            Reporter: Richard Wise


There are multiple problems that can cause the hbase shell to fail with the following logs:
{noformat}
NativeException: java.io.IOException: java.lang.reflect.InvocationTargetException{noformat}
And a ruby stack trace ending in hirb.rb:131 (which constructs the HBase client).

There is no information about the Java exceptions (e.g. message or stack trace) that allows the error to be debugger (even enabling debug logging does not show any more information), so the current way to debug is to reproduce the issue using the Java client to see the stack trace. This is clearly a very inefficient approach and would be resolved by including Java exception message information in the logs.
