Subject Region server web port doesn't respond
Date Tue, 05 Nov 2019 03:39:13 GMT
Hi all,

I'm using hbase 1.2.9.

Every time after starting regionserver several days, I cannot open its web
ui.

Using nc test tcp port, it's OK. But using curl, it just show 'curl: (52)
empty reply from server '.

Some abnormal message can be found in logs(in every minute):
