----------------------------------
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.
