lixiaobao commented on HBASE-22250:
-----------------------------------
I find the
{code:java}
//代码占位符
hbase.master.kerberos.principal
hbase.master.keytab.file
hbase.regionserver.kerberos.principal
hbase.regionserver.keytab.file
{code}
used in hbase-client model and hbase-server model ,so I add a class named
org.apache.hadoop.hbase.security.SecurityConstants marked IA.Private to
hbase-common model to gathering the constants.
> The same constants used in many places should be placed in constant classes
