A SSH connection with the standard port 22 to a default MapR5 (MEP 3.0) installation is successful, e.g. hostname:22. It is no problem to upload and download files via the remote file nodes.
But I experience some problems to start a connection with HDFS Connector or HIVE Connector. I would expect a connection string like hostname:8020 or hostname:10000 to connect. The database name is e.g. dbname_db.db stored at /path/hive/warehouse/dbname_db.db .
I get errors like:
WARN HDFS Connection 0:83 Couldn't connect
ERROR Hive Connector 3:1 Execute failed: Could not create connection to database: Connection timed out: connect
