             Summary: Avoid using RPCs when querying table infos for master status pages
                 Key: HBASE-19861
                 URL: https://issues.apache.org/jira/browse/HBASE-19861
             Project: HBase
          Issue Type: Improvement
          Components: monitoring
            Reporter: Xiaolin Ha


When querying table information for master status pages, currently method is using admin interfaces. For example, when list user tables, codes are as follows.

Connection connection = master.getConnection();
Admin admin = connection.getAdmin();
try {
 tables = admin.listTables();
} finally {
 admin.close();
}

But actually, we can get all user tables from master's memory.

Using admin interfaces means using RPCs, which has a low efficiency.
