[jira] [Commented] (DRILL-2785) Aggregate MAX query on a directory
fails with SQLException
[ https://issues.apache.org/jira/browse/DRILL-2785?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14494716#comment-14494716 ]
Jinfeng Ni commented on DRILL-2785:
-----------------------------------
The query plan looks fine to me. From the error msg, I think the cause of the problem is in the input data. Is there any field in your csv file which is not a valid number?
java.lang.NumberFormatException: ",fr
at org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.nfeL(StringFunctionHelpers.java:90) ~[drill-java-exec-0.9.0-SNAPSHOT-rebuffed.jar:0.9.0-SNAPSHOT]
If that's the case, I think it is expected that the query will hit this NumberFormatedException.
