------------------------------------
Summary: Namespace operations should throw clean exceptions
Key: HBASE-9510
URL: https://issues.apache.org/jira/browse/HBASE-9510
Project: HBase
Issue Type: Bug
Components: master
Reporter: Enis Soztutar

Fix For: 0.98.0, 0.96.0
Some of the namespace operations does not throw clean exceptions mimicking
table exceptions (TableNotFoundException, etc).
For example:
{code}
hbase(main):007:0> describe_namespace 'non_existing_namespace'
ERROR: java.io.IOException
