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}}
