Subject [jira] [Commented] (HBASE-18921) Result.current() throws ArrayIndexOutOfBoundsException after calling advance()
Date Mon, 02 Oct 2017 07:50:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18921?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16187734#comment-16187734
] 

Chia-Ping Tsai commented on HBASE-18921:
----------------------------------------

We don't have defined what should happen if the {{Result}} has no more elements. I prefer
throwing the {{NoSuchElementException}} rather than {{null}} or other exceptions. That will
be more readable.

> On a Result object, if current() method is called after advance() returns false, this
throws an ArrayIndexOutOfBoundsException. The expectation here is that it should return a
null value.
