No live data nodes in Sandbox

dmitrynheng — Fri, 16 Sep 2022 10:50:36 GMT

I installed Sandbox within VMWare running in Windows 10.

I noticed that Ambari dashboard reports 0 live data nodes. And this is probably why I can't write any file in HDFS.

Are data nodes not available in Sandbox upon install? Do I need to manually create them?

@Dmitry Otblesk , There is 1 datanode already installed in the Sandbox. Can you please try to start the datanode component from Ambari? Let us know about the error if you receive any.

However I am still wondering why HDFS does not start on its own, why do I need to start it manually? When I tried to run Sandbox within Virtual Box I did not have to start it, all worked automatically

@Dmitry Otblesk - Please turn off maintenance mode for HDFS to allow it to start with other services after reboot.
