Subject [jira] [Created] (IGNITE-5069) QueryWords example fails with exception
Date Mon, 24 Apr 2017 15:30:04 GMT
Yakov Zhdanov created IGNITE-5069:

             Summary: QueryWords example fails with exception
                 Key: IGNITE-5069
                 URL: https://issues.apache.org/jira/browse/IGNITE-5069
             Project: Ignite
          Issue Type: Bug
            Reporter: Yakov Zhdanov
            Priority: Blocker
             Fix For: 2.0

[~sergi.vladykin], please have a look. It may happen so that avg(cnt) in former Ignite versions
was returned as double for long column. For current master it is returned as long and causes
exception in formatter. I was able to reproduce it on 1.9 also, but did not try other versions.

Steps to reproduce
# start {{ExampleNodeStartup}}
# start {{QueryWords}}
# start {{StreamWords}}
