> hbase 96.0(probably the same issue on 94.x) on single node cluster. At some point, we
stopped Hadoop, but keep hbase running. As expected, hbase began to throw connection errors.
 
> P.S., later testing shows that this problem doesn't limit to single node cluster. 
> For the first hour, the regionserver log grows by ~10MB, and master log doesn't grow
much,  which is ok.

disk space.
