I had to chnage my zookeeper to upgrade its physical memory so I added a
new one and removed the old one, while doing so I received an error so
after that I inialized it and it worked again properly.

But it seems that this action was a disaster everything was not working,
so after doing alot of actions thanks GOD HDFS is working properly. But
hbase is not at all, hmaster doesn't want to start it produces this error:
