Nicholas Jiang commented on FLINK-19064:
----------------------------------------

[~jark] I guess the meaning of [~ZhuShang] is that the javadoc of the method 
configure() is Creates a \{@link Scan} object and opens the \{@link HTable} 
connection, which means that HBase connection is defined to open in configure().
