Subject [jira] [Commented] (DRILL-4339) Avro Reader can not read records - Regression
Date Tue, 02 Feb 2016 20:24:39 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15128954#comment-15128954

Jinfeng Ni commented on DRILL-4339:
-----------------------------------

On a second thought, seems that it's easy to change the function setColumn's signature. That
will avoid the re-compile. However, without re-compile, I'm not sure if your customer storage
plugin will work or not, since the implementation of this method actually is changed in 1.5.0.
