Subject [jira] [Commented] (DRILL-4946) org.objectweb.asm.tree.analysis.AnalyzerException printed to console in embedded mode
Date Mon, 17 Oct 2016 03:24:58 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15581070#comment-15581070
] 

Jacques Nadeau commented on DRILL-4946:
---------------------------------------

For reference: the scalar replacement code is known to not work in some situations. In those
situations, in production, we fallback to skipping it since it is simply a performance optimization.
In development tests we fail queries so we don't accidentally introduce scalar replacement
regressions.

is printing stack trace to stderr.
