Hi I am using knox 0.6.0. As per https://issues.apache.org/jira/browse/KNOX-546 "this scenario is only true in a secure cluster setup." I am not using secure cluster setup. so not sure this will solved my scenario or not. I observed one more thing hang will happen during creation of hbase table and putting a data inside that. same functionality is working fine with older knox version 0.5.1.
can i report this as a bug? if yes then please let me know the steps to report as a bug.
