Known Issues

See also the Known Issues of version 2.6.1.
CDAP works only with node.js versions 0.8.16 through 0.10.36.
When the CDAP CLI starts up, it auto-connects to localhost. After a connect <hostname> command is issued from within the CLI, all operations will work except for Explore queries (the command execute 'query'), as the Explore Client doesn't pick up the change of hostname. A workaround is to start up the CLI with the environment variable CDAP_HOST set to the desired hostname, so that the CLI autoconnects to that host on startup. This has been fixed in an upcoming release (2.8.0) of CDAP.
