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.
