Dataproc cluster fails to initialize

Question

With the standard dataproc image 1.5 (Debian 10, Hadoop 2.10, Spark 2.4), a dataproc cluster cannot be created. Region is set to europe-west-2.

The stack-driver log says:

"Failed to initialize node <name of cluster>-m: Component hdfs failed to activate See output in: gs://.../dataproc-startup-script_output"

Scanning through the output (gs://.../dataproc-startup-script_output), I can see the hdfs activation has failed:

Aug 18 13:21:59 activate-component-hdfs[2799]: + exit_code=1
Aug 18 13:21:59 activate-component-hdfs[2799]: + [[ 1 -ne 0 ]]
Aug 18 13:21:59 activate-component-hdfs[2799]: + echo 1
Aug 18 13:21:59 activate-component-hdfs[2799]: + log_and_fail hdfs 'Component hdfs failed to activate' 1
Aug 18 13:21:59 activate-component-hdfs[2799]: + local component=hdfs
Aug 18 13:21:59 activate-component-hdfs[2799]: + local 'message=Component hdfs failed to activate'
Aug 18 13:21:59 activate-component-hdfs[2799]: + local error_code=1
Aug 18 13:21:59 activate-component-hdfs[2799]: + local client_error_indicator=
Aug 18 13:21:59 activate-component-hdfs[2799]: + [[ 1 -eq 2 ]]
Aug 18 13:21:59 activate-component-hdfs[2799]: + echo 'StructuredError{hdfs, Component hdfs failed to activate}'
Aug 18 13:21:59 activate-component-hdfs[2799]: StructuredError{hdfs, Component hdfs failed to activate}
Aug 18 13:21:59 activate-component-hdfs[2799]: + exit 1

What am I missing?

EDIT

As @Dagang suggested, I ssh-ed into the master node and ran grep "activate-component-hdfs" /var/log/dataproc-startup-script.log. The output is here.

So the problem is there is an user name called "pete{" on which the hadoop fs -mkdir -p command failed. These kind of user names with special chars especially open parenthesis e,g,"()[]{}" will potentially fail the HDFS activation step during cluster creation.

So the easy solution is just to remove those accidentally created user.
