You can not successfully deploy hive clusters with Hive guidance documents

When I follow the official document from cwiki https://cwiki.apache.org/confluence/display/Hive/GettingStarted to build Hive2.1.1 single node service encountered several problems::
1, the following to create the HIVE warehouse directory needs to be modified
  A $ HADOOP_HOME / bin / hadoop fs -mkdir /user/hive/warehouse
  B $ HADOOP_HOME / bin / hadoop fs -mkdir -p /user/hive/warehouse
Using B instead of A might be better
2, the following two description positions need to be adjusted
A.Running Hive CLI
To use the Hive command line interface (CLI) from the shell:
   $ $HIVE_HOME/bin/hive
B.Running HiveServer2 and Beeline
Starting from Hive 2.1, we need to run the schematool command below as an initialization step. For example, we can use "derby" as db type.
   $ $HIVE_HOME/bin/schematool -dbType <db type> -initSchema

When I execute the $HIVE_HOME/bin/hive command, the following error occurs：

When I execute the following order, and then the implementation of hive order problem solving:
$ HIVE_HOME/bin/schematool -dbType derby -initSchema
