Start hbase error report

Could only be replicated to 0 nodes instead of 1

Hmaster does not start up

I have investigated a lot of similar problems, and most of them deal with them in a violent way.

As it is a test environment, do not dare to be too violent, so as not to spend energy to deal with these crap.

. / bin/hadoop dfsadmin-report

find

1 uneven distribution of data on datanode

2 one of the datanode is full

Clear the space decisively, and after hbase restarts, the problem is solved.
