Hbase error while executing ./bin/start-hbase.sh (windows)

I installed Hadoop with this tutorial https://www.youtube.com/watch?v=g7Qpnmi0Q-s and it´s working. I installed it in C:/hadoop.

I installed it only because I read that hadoop is a prerequisite for executing (no single mode) and the error messages are regarding some hadoop configurations. But it didn´t help.

I tried to install Hbase with this tutorial https://ics.upjs.sk/~novotnyr/blog/334/setting-up-hbase-on-windows. But I´m getting this error while executing ./bin/start-hbase.sh

Output in cygwin terminal:

$ ./bin/start-hbase.sh

SLF4J: Defaulting to no-operation (NOP) logger implementation

The error output produced by start-hbase.sh has three different errors.

1. Issue with HADOOP_HOME variable

WARNING: DEFAULT_LIBEXEC_DIR ignored. It has been replaced by HADOOP_DEFAULT_LIBEXEC_DIR. WARNING: log4j.properties is not found. HADOOP_CONF_DIR may be incomplete. 
ERROR: Invalid HADOOP_COMMON_HOME

Update the Environment variables with HADOOP_HOME pointing to the Hadoop installation folder (not the bin folder within the installation folder).

As per your setting, 

HADOOP_HOME=C:\hadoop\

Additionally, set the location of the configuration files

HADOOP_CONF_DIR=C:\hadoop\etc\hadoop\

2. Issue with interpreting Linux style path or Invalid path

cygpath: can't convert empty path

In hbase-env.sh (under C:\Java\hbase-2.2.4-bin\hbase-2.2.4\conf\), update the values for HBASE_HOME and HBASE_CLASSPATH

As per your installation,

export HBASE_HOME=/cygdrive/c/Java/hbase-2.2.4-bin/hbase-2.2.4/
export HBASE_CLASSPATH=/cygdrive/c/Java/hbase-2.2.4-bin/hbase-2.2.4/lib/

And in your environment variables, make sure HBASE_HOME is configured similar to HADOOP_HOME.

3. Unable to resolve hostname

: Name or service not knownstname laptop-l6543teb

Update your hosts file with correct IP - Hostname mapping.
