be larger than your VM. Check “Reserved Space for Non DFS Use” in the
DataNode settings in CM (Services > HDFS > Configuration > DataNode). Make
sure that this is set to a much smaller value than the size of your VM disk.

Data node is running fine; there are no errors in its log.
Yes, this is VM, and there is plenty of space available.
I have changed the replication factor to 0 but the problem persists (after
restart of services).
This is brand new installation so there is practically no data. I can't
eve open the HBase Web UI because of this error.
Regards,
Alex

Any chance this pseudo cluster is on a virtual machine, Alex? If so, how
much hard drive space did you allocate to the VM?

I have changed HDFS replica factor to 1.
Errors in the log files complain that files could only be replicated to 0
nodes instead of 1.
Has anybody tested with a single node?
Is there a setting I need to change to make this work?
Is your datanode running? Do you see errors in the DN log?
